I appreciate the modesty OP.
Another one is Smoking. Nothing against the people who smoke, but the act. IMO, its the worst smell in the world and whenever I smell it my throat closes up and its hard to breathe. I don't have asthma or anything, but It just so bad. Even more when you ask people to put it out, and they just give you the finger.
It depends. If you have no authority, then don't ask me to put it out. You deserve the finger if you feel entitled to tell me to put out my smoke. Cops don't even make me put out my smokes since I'm over 17 years of age, what makes you think I'll listen to you?
Alright ranting over. You have anything that irks you?
What was said above. Also, people with computers like you mentioned. Novice programmers trying to talk down to me. Plus a lot of social things, of course.
