I go through friends pretty quickly, anyone else do this too? is it strange?

I have a pretty good amount of friends, but I'm not really that close to anyone, and I don't really see the need for it. I pretty much get a different group of friends every year and don't really talk to old friends afterward. I just noticed this a few weeks ago wen I was texting some people and they all seemed to talk to friends they have had for years. I'm just a bit confused.
