i was actually talking about this with people the other day.
worst thing i've said is to my stepdad, i told him that nobody loves him or cares about him. that his wife and son hate him, he has no friends, and his parents don't even give a shit about him. and that nobody would care if he dies. my mom was sitting right there and didn't even say anything because it's all true.
worst thing i've done, umm i remember when i was a kid me and my friend got into a physical fight and i started choking her and she started crying and told on me. and i just kept lying and saying i didn't do anything and she was making it up and everyone believed me.
