What is your relationship with your close friends?

So I’m a college student and recently I’ve noticed that bond between some of my close buddies from High School and I is slowly weakening as time goes on.

Now don’t get me wrong, I’m okay with this and understand this. We’re not the same guys and gals we were back in the day. They’ve met new people, I’ve met new people, and we all just kind of grew up and moved on.

But it got me wondering, preferably for those out of grade school, what is relationship you share with your friends? Were they, like me, grade school buddies, co-workers, people you met at Church or other religious services, childhood friends, some random person you met on a plane, etc?

I’m not sure if relationship is the best word to use here. If someone has a better word, please suggest it.
