Social anxiety is a terrible burden, because you're never 100% sure (or even 51% sure) of what other people intend with their verbal or non-verbal communication. I know what to do when someone says "Thank you", and I know what to do when someone says "Thanks", whether or not they really mean it. But what the hell does it mean when someone writes "Thank you", and then scratches it out and writes "Thanks" instead? What the crap does THAT mean? And I'M the weirdo?
