It's so crazy catching up with old friends. You find out so many things you never thought possible. I feel like most of my friends who I lost touch with all had kids and/or got married. It's even weirder when some of those friends are ex's. Sometimes I'm not sure how to feel about that. Either they're moving too fast or I'm moving too slow in life. I can't even keep a relationship let alone a marriage! 
but we all have to move at our own pace in life...
