Speaking in absolutes in serious discussion is a borderline trigger. When I'm joking, I tend to be hyperbolic, but aggravated use of "always" and "never" is upsetting. I try as often as possible to use I-statements (I feel ____, I think ____) because I know how much I appreciate it when others do too. If I had to tie it to my typing, I think it's an e2 hang up over not receiving credit for all the agonizing and labor intensive sacrificing I do for everyone. That was a joke but I seriously hate when my efforts are treated as if they aren't valid or somehow don't count. "You never do so and so" after me literally doing so and so pisses me off. At the very least say "You never do so and so to my standards" or "It seems like you never so and so". That way it isn't a spit in the face.
Talked about it on Discord before, but if your writing is difficult to read aloud, I'm mad. I read through posts on here pretty thoroughly and it stresses me out when I can't understand you. Bad spelling, poor grammar, improper bbcode formatting, it's too much. Just... reread your posts before you send them! I can understand the occasional 'from the phone' typo, but the 'Go Advanced' button is right there. You can press 'Preview Post' before sending it. You could've easily fixed pressed enter twice in between paragraphs. WHY ARE YOU SO BAD AT WORDS? It's probably a symptom of uptight ESTJism.
Speaking of which, I hate hate hate when people mutter. Speak up or stop making noises. Not type related, I just have terrible hearing.
Also people who are weird about eye contact are suspicious. I always look people in the eye, it's pretty rude not to. Same with poor handshakes. That could also be an ESTJ thing but I have a feeling it's a #SouthernValues thing.
