This is such a big thread that I couldn't read it all, so sorry for not numbering, and I apologize if these have been covered already.
Saying something other than what you mean and expecting me to be able to understand your nonverbal, subtle hints. Sorry but I don't do subtlety. You have to use that thing God gave you called a voice.
Not coming to me directly and talking to me if I have upset you, but rather, just avoiding me, or even worse, talking to my mom about it. Excuse me, I'm 28 years old. You can deal with me as such.
Deliberately using words that trigger my bizarre form of audio/tactile synesthesia in a bad way, or mispronouncing words that trigger it in a good way to mess with me. I try not to correct people if they use one of these words, as unfortunately some of the words are pretty common and can't be avoided, but if you know me and I have told you that it bothers me when you say this word, and you do it anyway, that is annoying. To clarify, my special interest, or one of them anyway, is plushies (teddy bears, etc.) If I hear someone use the term stuffed animals, I get a bad trigger and it feels like my guts are crawling *shudder*. My mom has a horrible habit of using that infernal phrase when speaking to me about my plushies. I'm like, dude, you know it gives me a bad trigger, so why in the name of all things sacred do you keep using it insistently? I understand that you can slip up, as unfortunately it's a common expression and people use it without thinking, but she doesn't even try, and usually when she says it she is in a bad mood so it is wise not to correct her.
