A criteria
I think I've decided for myself that after a certain margin I expect friends to initiate activities or hanging out to some extent. I found myself walking home with them and they mentioned how they went climbing again. I originally had been waiting for them to initiate and figure out when we could go climbing, and they never did. Or anything else for that matter outside of a class group setting. I even saw them one day climbing with some friends, and they even mentioned how one of our friends was also free that day. There's a big chance that friend instigated to them, but I can't give this much consistent benefit of the doubt. I find this ship sailing more and more. But also I'm finding this as a nice experience of understanding what I expect from friends, and having self worth to know what not to tolerate.
