Why does someone who insists he will never join Facebook, join anyway? Because he wants to see who from his high school class still looks good. That's why.
And how does he avoid his relatives, who he barely talks to, from finding him? He uses a fake name. But that does not really work when you become friends with other people they know.
So, you go ahead and accept them and think, "Maybe, I will start talking to them and be the adult that I am. Let the past be the past." Here's to hoping.
And, by the way, the cute one's from high school, well... didn't remain that way. And some of the one's you don't even recall... HAWT. Later.
