For some reason it really bother's me when people have to make noise all the time and I have had several roommates and coworkers who constantly make noise.
Those weird squeaky noises when they stretch their arms over their heads.
Humming ALLL THE TIME.
What? Are you afraid of silence?
If you need noise, by all means put on some music. Other wise KNOCK IT OF.
YOU'RE DRIVING ME CRAZY!
