How long on average do your friendships with people last? What's the longest friendship you've had?

@Kaleidoscopieceyes you know i used to think i had friends like that but they didn't hold up against distance, so i think you have it right when you say that they are more like family because i believe that families have a deep rooted connection that keeps them together. I'm not speaking biologically as more in people the individual considers their family.
