I have this thing about noises. They can drive me noix (pardon my French). Loud talkers on the bus. Restaurants that feel the need to crank the tunes, so everyone has to yell.
That high-pitched laughter coming from the party next door. (Annoying because of the sound, but also because I’m a part-time grouch and I’m easily angered by laughing people — even though I love to laugh myself.
