What kind of noises really irritate you?
I live in a city, so we hear sirens, people, and loud talking. That I can deal with. One thing that drives me nuts are foot steps in the apartment above me, or the people upstairs dropping things.
I also hate the sound of crying babies or a dog barking.
Some people abhor odd sounds like sneezing or coughing.
Which noise do you find the most irritating?
