First, a man does not call a relationship a relationship - he refers to it as "that time when me and Suzie were boinking on a semi-regular basis."
When a relationship ends, a woman will cry and pour her heart out to her girlfriends, and she will write a poem titled "All Men Are Idiots." Then she will get on with her life.
A man has a little more trouble letting go. Six months after the breakup - at 3 am early on a Sunday morning - he will call and say "I just wanted you to let you know you ruined my life, and I'll never forgive you, and I hate you, and you're a total floozy. But I want you to know there's always a chance for us." This is known as the "I Hate You/I Love You" drunken phone call, that 99% of all men have made at least once. There are community colleges that offer courses to help men get over this need; alas these classes rarely prove effective.
In the locker room, men talk about three things: money, football, and women. They exaggerate about money, they don't know football nearly as well as they think they do, and they fabricate stories about women.
Women talk about one thing in the locker room - sex. Not in abstract terms, either. They're graphic and technical, and they *never* lie.
