I don't really know what to say. I'm sure you're not alone in having idiosyncrasies and obsessions however. And my guess is you do things that annoy other people as well. Such is life.
I try to avoid situations that I know will bother me (it is my problem after all). I never, and I mean never, eat from buffets. I find it nauseating so I don't do it. If I know someone is a slob when they eat, I don't eat with them. I hate the noise of people eating in a theater. I bring my headphones and listen to music (why must people eat in theaters anyway? Disgusting, low quality, expensive crap. Can Americans NOT eat for a couple of hours? Another one of my 'issues'....American obsession with consuming anything that can't run away from them
) I usually can ignore it after the movie starts. Ice chewers? Please stop
Gum chewers? Mints. Please. Hahaha. And the list goes on and on and on.
And its ALL my problem.
