It would be very annoying to most people but competition is a daily normality for boxing twins Gavin and Jamie McDonnell, who could become the first British identical twins to win world titles.
He would still be fighting at Donny Dome if I didn't help him out.  He got a leg-up from me
"This is massive because I don't know any other twins in the country that have done what we've done," said Gavin, who is unbeaten in 18 fights and faces Mexico's Rey Vargas, 26, for the WBC super-bantamweight title in Hull on Saturday.
"To be the first to do anything is an achievement in itself. Our kid Jamie has done a few things like that. He was the first European and world champion from Doncaster so I can't get them but to be the first twins means I get a bit of room on the stage."
The charismatic Doncaster duo, both 30, have each collected a pair of British and European titles but at different times.
Of course the main achievement that separates the two is Jamie's current status as the WBA bantamweight world champion - he has also previously held the IBF version.
Gavin turned pro in 2010 - five years after his brother - but has quickly risen through the ranks and sees his next fight for the prestigious green and gold WBC belt as a chance to step out of Jamie's shadow.
"I'm being compared to him all of the time. He's Mr Bee's Knees, who's done everything - it takes the shine off my fights," said Gavin.
"Nobody wants to be a number two at anything. He's been number one all his life and now I'm giving him a taste of his own medicine. He's number two now if I win the WBC title. He's got the other belts - IBF and WBA, but if I can say, 'who's got the best world title?' No comeback."
But with twins there's always a comeback and Jamie duly interrupts: "You then have to defend it five times to be on a level with me.
"You only have that fight because you were in my ear saying, 'Get me in with Eddie Hearn [the McDonnell brothers' promoter],' so I got him a meeting with Eddie and I said, 'help him out Eddie, will you?' He would still be fighting at Donny Dome if I didn't help him out. He got a leg-up from me."
Gavin's task on Saturday is no easy one as he goes up against a man unbeaten in 28 fights, with 22 knockouts. But promoter Hearn reckons the "down and dirty" Hull Ice Arena will give him an advantage.
"We had decent money on the table to go to Mexico for this fight but I thought Hull Arena can do strange things to a man," said Hearn.
"When you go in those changing rooms and walk out, it's a bear pit. If you're going to beat Vargas - a brilliant fighter - you have to make him feel uncomfortable.
"He has to open the door to the changing room and go 'what is this?' We need every advantage we can get in this fight."
He may seem the confident twin now but Gavin does admit he would not be boxing if it were not for his brother's achievements.
"If it wasn't for Jamie I'd be in the pub with the lads and working a 9-5 job," said Gavin, who worked as a plasterer alongside his twin.
"I never had an ambition to become world champion. I knocked boxing on the head at about 16 because I wanted to go out with my mates. But I saw Jamie at all his fights and saw him win titles. I didn't think I would do that but I wanted to have a go.
"Now I'm fighting for a world title and I believe I can win one. My brother's done it and I believe I can do it."
If Gavin cites his brother as inspiration, Jamie can now see the motivational benefit of such a close-knit rivalry.
"We push each other. Now he motivates me," said Jamie, who suffered the last of his two defeats in 2008.
"I've got to step it up otherwise people will say your brother's overtaking you and I can't have that. We're not jealous of each other. We are just born winners."
The pair are typical twins, always trying to get one over on each other in anything, from their follower numbers on social media to who could build the better house. But as their boxing profiles grow rapidly, there remains a problem.
"We get mistaken for each other all the time," said Jamie. "If someone calls me Gavin, I just go with it."
Gavin adds: "There'll be a tweet saying, 'Great to meet world champion Jamie McDonnell' and it was me. That makes me steam a little bit because I'm not a world champion yet."
There have already been world champion twins - the American Charlo brothers, Jermell and Jermall, own IBF and WBC belts in the light-middleweight division. The McDonnells aim to go one step better by one day completing the WBA, WBC, IBF and WBO four-piece set.
"We could get all four between us," said Gavin.
"The question is, whose mantelpiece will they go on? I'm sure we can collect them all in a few years because how many twins have done that? I think every fight for me now will be big fights at the top alongside him."

The proposed link would include a 3.1 mile (5km) tunnel between the Great Western main line at Slough in Berkshire and the airport's Terminal 5.
But Network Rail said a planning application, due to be submitted in the next few weeks, had been delayed until late 2017.
Businesses said the link was needed to attract more people to Reading.
Nick Halstead, who owns technology business Datasift in Green Park, said the "disappointing" delay was making it harder to attract staff.
He said: "The delay is not a good sign for this project and other projects where Reading should be seen as important."
Slough Labour MP Fiona Mactaggart said the delay showed "a failure of leadership" by the government and was "pathetic".
Tim Brownstone, who runs Reading sportswear company Kymira, said the rail link was needed to bring external investment to the area.
In November, a review of Network Rail's investment programme by Sir Peter Hendy concluded a number of projects including this one would take longer than planned.
Julian Burnell, from Network Rail, said the delay was "not really anybody's fault"  and changes had to be made following the Hendy Report.
He said: "It's a brand new tunnel, it's an entirely new stretch of railway, and that takes a lot of time and a lot of careful planning."
A Network Rail spokeswoman added consultations with landowners and interested parties in the area also had to be completed.
Given the go-ahead by the government in 2012, it was originally planned the new service would be in operation by 2021.
The plan would save up to 30 minutes for passengers travelling from south Wales, the west of England and the Thames Valley.

After closing at a record level of 7,142.83 on the final trading day of 2016, the FTSE 100 rose another 0.5% to close at 7,177.89.
"No January blues for equity markets as traders in London have returned to their desks in optimistic mood," said Neil Wilson at ETX Capital.
"The FTSE is still enjoying the momentum from last week's Santa rally."
Banks and financial companies were the strongest performers with stock broker Hargreaves Lansdown up 5% and the bank Barclays up 3.78%.
Changes to broker ratings were behind some of the day's biggest moves. Intercontinental Hotels Group rose 1.3% after Barclays raised its rating on the company to "overweight".
But shares in Halfords and Next were both hit by downgrades from Deutsche Bank. Halfords fell 5.6% after Deutsche cut its rating on the company to "sell" from "hold".
Next - which is due to release a trading update on Wednesday - fell 4.2% after Deutsche Bank downgraded its rating on the retailer to "hold" from "buy".
A stronger than expected survey of the UK's manufacturing sector boosted the pound. The latest Markit/CIPS purchasing managers' index for manufacturing suggested activity in the sector hit a two-and-a-half-year high last month.
