Yeah! Some noises just stand out as particularly annoying.

I had a friend who could hear security systems around jewelry displays.

My hearing isn't "hyper", just "sensitive."

I wanted to throttle the guy behind me in church who was clipping his nails! (Doesn't bother me when I do it though.)

Don't repeatedly click your pen around me, please. Or hawk and spit.

I cover my ears when someone gets out of my car and "slams" (not really) the door.

But its alright if you wanna crack your knuckles, cause I do that too!
