nomekop55555, it's very hard for me to stick with just one thing. There are a lot of ideas that pop into my head for avatars, so I frequently change it up.
I do like to stick with one avatar for a while though, but I don't have a lot like that.
My school is pretty small as well. It only has 300 people. My school does have to seperate buildings. Middle schoolers are kept in different buildings than the other kids.
