rhymes-with-heaven:

Don’t you hate it when your friends change? They aren’t the person you befriended at first. Sometimes it’s a small change that doesn’t really affect anything or a change for the better. But other times it’s not. And it’s those times when you realize that if you met them today, you wouldn’t have become friends in the first place. And you feel bad when you stop being friends, but you realize that the person you are mourning has been gone for awhile.
