It is kind to hose people in your home.
Lorne's old friend from college just called him to ask him if him and his wife could stay at Lorne's place while they are visiting Lorne's city.
Lorne wants his house to be tidy and impeccable at all times.
Lorne accepts to house his friend and his wife and asks them to put all their stuff in one room while they're visiting.
Lorne turns down his old friend because he doesn't want to end up with a mess of suitcases and clothes in his house.
Lorne's friend is delighted to see Lorne again and enjoys his time with him.
Lorne's friend is very disappointed and feels Lorne let him down.
