God the list is so long but
-People who send multiple messages instead of putting it all in one message.
"Like"
"This"
It drives me up the wall. Put it in one message or just don't bother
-Any loud eating noises is just...unbearable. Please. It is not that hard to chew with your mouth closed, yeah?
-When politics get brought up when they have nothing to do with the conversation. Leave it alone, sometimes people just wanna have a conversation
-Hating on people for who they choose to love or who they choose to identify as. Why does it matter to you? They aren't hurting you :/
-Just overall being a genuine crappy person to others for no reason. Why? Why do you feel the need to treat people like trash for no reason other than your inflated ego?
-SNOOPING. Whatever I do on my phone/write in my journals/draw in my sketchbook is /my/ business unless I show you. Stepmom used to read through my messages when I was younger and confront me about things I said. She also liked to read my diary. Imagine how bad my trust issues are.
Anyway I think that covers most of the bases...
