Seems like all my friends are either getting married or moving away. Honestly, though, I still hang out with my crew from high school, and we're probably one of the tightest groups of friends I've ever heard of. We're verbally abusive to each other, but it isn't malicious - it's entertaining.
I know what you're talking about. Two of my friends are like this, but I only see them a few times a year. Actually, they're due for a visit soon... kickass.
