PROBLEM: After failing to convince the British people of the need to Remain in the European Union, Prime Minister David Cameron knew that his time was up. He felt he was not the right person to lead the country.
Without waiting for street protests or endless appeals from the United Nations, Mr Cameron announced his resignation, giving way to someone better equipped to manage the new situation that Britain found itself in.
Africans can now appreciate that there is no need for melodramatic performances when it comes to leaving office and importantly, not unusual for a leader to step down before his term ends.
It is even possible to go out on a jaunty note, as Mr Cameron did, whistling to the tune of D'Banj's Olorun Maje.
Immediately after Britain voted to leave the EU, the country's political establishment was thrown into chaos.
The uncertainty in the currency markets led to the pound falling to a 30-year low. And confidence in doing business in the UK seemed to be ebbing.
The UK's unity was in jeopardy, with the possibility of Scotland pulling out of the union.
Britain was facing a crisis.
But the country did not accuse the international media of presenting an exaggerated impression to the world of how bad things were.
They did not sit back and watch their country fall completely apart, before they took action.
As quickly as possible, the ruling Conservative party did away with the prospect of a prolonged leadership battle, recognising that collective energy was better expended on tackling the looming crisis head on.
Experts who had warned of turmoil if the Leave campaign won rehashed their predictions but they started offering solutions on how the UK would cope with life outside the EU.
The Chancellor of the Exchequer who had campaigned for the Remain side quickly changed gear and declared that Britain was "open for business".
Adaobi Tricia Nwaubani:
"Theresa May has not ordered that Larry be thrown out on suspicion of being a witch in cat form sent by political enemies to spy on her or pull her down"
And as soon as Theresa May took over, she announced her cabinet without much ado, everyone expected to begin work immediately.
No time for lengthy, and televised, courtesy calls from her villagers and church members and the market women association and the traditional rulers and her old girls association and her husband's villagers - all of them wanting her to know, via hours-long speeches, that they support her and wish her well.
As far as we know, Mrs May spent her first night in office at Number 10 Downing Street, the official residence of the British Prime Minister, never mind that she may have stayed awake all night drawing up her cabinet list.
How many African leaders would dare do such a thing? Occupy a residence just vacated by a predecessor without first inviting native doctors or shamans or pastors to sanctify the place and cleanse it of any spiritual booby traps, while commanding the witches and wizards lurking in the woodwork to either return to sender or fall down and die.
And Larry the cat is being allowed to stay.  The stray feline has lived in Downing Street since 2010, playing the role of chief mouse chaser.
Mrs May has not ordered that Larry be thrown out on suspicion of being a witch in cat form sent by political enemies to spy on her or pull her down.
You need only watch a random selection of Nollywood films, which are immensely popular all over Africa, to understand that a stray cat in this part of the world is never just a stray cat.
Not to talk of a stray cat inherited from a political predecessor.
The UK is not in any way a perfect place.
The country itself can learn a few things from the diverse ways of the African people.
But, when it comes to the matter of Mr Cameron's handover to Mrs May, we would do well to sit at the feet of Britain and learn.

SOLUTION: In our series of letters from African journalists, novelist and writer Adaobi Tricia Nwaubani looks at the spate of resignations in the UK after the vote to leave the European Union and asks whether there are any lessons for Africa.

PROBLEM: Black, 52, was filmed apparently naming staff at other clubs who could be induced to pass on information about players to a company for money.
Such payments would be against Football Association rules.
Black, who oversaw Aston Villa's final seven Premier League matches last season, has denied the allegations.
"It doesn't take too much to get these people involved," Black says in the covert recording.
"They won't have an awful lot of money."
Former Aberdeen striker Black quotes a figure of "a couple of grand", which the Telegraph claims was his suggestion of a suitable payment to an unnamed assistant coach at a Championship side in return for introducing players to the undercover reporters' fictitious agency.
Black denies suggesting that any football official should be paid, saying that his "couple of grand"comment related to a freelance scout that an agency looking to break into the football industry might approach.
A spokesperson for Black said his client did not recall the possibility of bribing officials being mentioned.
"This was not the purpose of the meeting so far as our client understood it. Any suggestion that he was complicit in such discussions is false," the spokesperson added.
Southampton said they were "fully committed" to investigating the claims and intend to work closely with the Premier League and Football Association on them.
Black has held permanent managerial posts at Motherwell and Coventry, as well as having caretaker spells at Birmingham, Sunderland, Blackburn, Rotherham and Villa.
His played for Aberdeen and French side Metz and won three caps for Scotland before he became a coach at Celtic.
The allegations about Black are the latest from the Daily Telegraph's investigation into corruption in football.
On Thursday, Barnsley assistant boss Tommy Wright was sacked over claims he took cash for trying to engineer certain transfers. Wright has "categorically denied" the claims.
Sam Allardyce left his post as England manager on Tuesday, making a "whole-hearted apology" in the wake of allegations in the newspaper that he offered advice on how to "get around" rules on player transfers.

SOLUTION: Southampton assistant manager Eric Black gave undercover reporters advice on how to bribe officials at other clubs, the Daily Telegraph has claimed.

PROBLEM: The British duo dominated from the start as they finished 2.62 seconds ahead of France with Germany in third.
Two other Coleraine men Alan Campbell and Peter Chambers failed to reach the A finals in their events.
Single sculler Campbell and lightweight four team member Chambers will compete in B finals on Sunday.
The lightweight pairs is a non-Olympic class but the performances of Cassells and Scrimgeour could put them in contention for promotion to one of Britain's Rio berths for next year.
Earlier this season, Cassells and Peter Chambers won the European title in the lightweight pairs class.
Chambers and his team-mates could only manage fourth in their lightweight four semi-final with Campbell fifth in his single sculls semi-final in Aiguebelette.
The Coleraine men will attempt to secure Olympic Games spots in Sunday's B deciders.
The top five finishers in the lightweight four B final will clinch places in Rio for their countries while Campbell, 32, will need a top-three finish in his B decider to book a British berth in Brazil.
2002 Olympic bronze medallist Campbell, who missed out on selection for last year's World Championships, was always going to be up against it in Friday's semi-final.
London Olympics winner Mahe Drysdale powered to victory in 6:45.08 which left him ahead of this year's European champion Damir Martin of Croatia with 2008 Olympic gold medallist Norwegian Olaf Tufte edging out Belarus's Stanislau Shcharbachenia to take the final qualifying spot.
Campbell was a further 3.21 seconds back in fifth spot.
Chambers and his British team-mates Jonathan Clegg, Mark Aldred and Chris Bartley were never really a factor in their semi-final as they finished 7.33 seconds behind Switzerland with France and Italy also progressing to the A final.
The British quartet's performance continued their recent struggles after they also failed to make the A final at the recent Lucerne World Cup regatta.
Richard Chambers and Will Fletcher will race for Britain in the lightweight double sculls final on Saturday.
Ennisillen woman Leonara Kennedy and her Irish team-mate finished a distant fifth in the final of the non-Olympic women's four final on Friday.

SOLUTION:
Coleraine rower Joel Cassells and his British team-mate Sam Scrimgeour have won the lightweight pairs gold medal at the World Championships in France.
