That feeling when your friends leave you out of something. You run through some scenarios in your head like, did they even know? Maybe they just forgot about you? Maybe they just thought you were doing something else? But when it comes down to it, they didn't even ask so you know the ultimate net meaning of it all is that they don't really give a shit about you.

Can't wait to move out of this miserable shit city and carve a life out for myself somewhere new.
