I'd like to get married one day, ideally by the time I'm 30.
Back in college, I guaranteed my best friend the best man spot, he already knows.
I'm his best friend too, so it was an easy decision.
I've known him for almost 20 years. I know 2 more best friends (1 guy, 1 girl) the same amount of time, as we all went to the same infant school, but I am in contact more with my main best friend than the other, but in about equal contact with my best girl friend.
When I had appendicitis, all 3 of them came down to visit me, either at the hospital or at home.
What further cemented it for me though was when my cousin's boyfriend had 2 season tickets to a Manchester United game vs Wigan Athletic, and he couldn't make the game, so gave me the 2 tickets for me and a friend. Out of everyone I could have picked to go with, he was the one I called first.
