I'm not sure if it's just that i'm really weird for doing this, but sometimes my mind will start conjuring up some kind of hypothetical scenario, and feeling really sad over the idea. For some reason i recently had one where i couldn't stop picturing somebody going to the painstaking effort of setting up one of those "guess how many x are in this jar" tables for a community event, and nobody caring. There's something about people making a real effort at something, and nobody noticing, that really gutpunches me emotionally.
So i spent like an hour unable to stop feeling bad for this hypothetical person my brain had come up with in a situation that wasn't happening. I felt so dumb for feeling that way too. I'm also that odd kind of person that feels sad for the chair at a meeting nobody sits in, god only knows why. Silver lining though, it's cool that i'm getting in touch with my feelings enough i don't feel particularly embarrassed these things happen any more. It's refreshing not to just shove that down in silence because "my feelings are stupid, and everyone is better off not hearing them."
