3 types of friends

I have a good bit of different kinds of friends. Some I feel wouldn't get along with my other friends. One kind I have are my work friends, they aren't really my friends we just work together but i enjoy working with them. Some I enjoy talking to but I don't talk to them like I do other people because they are different. They do make work more enjoyable. I have my favorite friends which are mostly like 4 people. Those are the friends i'm closing to and talk to more personally even though I don't see them a whole lot. I still hang out with them and we always have fun. these are usually the best friends I can be more myself around. I have school friends that I recently made because i guess they thought I was cool. They are kinda dorky but that's what makes them cool I see them more that my closer friends. They are more chill than my work friends.
