Well, I'm oficially "sensory defensive" so A LOT of things bother me. When I'm stressed, little things such as a key board or paper shuffling can really upset me (makes taking tests hard) and otherwise I HATE BEEPS!!!!!!!!!!!! My alarm clock pisses me off, those phones that beep make me want to slap them and break it, the tiny watch beeps and the car radio tuner make me really mad!!!!!!!
Other than that gum and food being eaten bother me emmensley.
