the neighbor's dog barking (because it means at least 30 minutes of that loud noise, over and over and over..........)
DD11 coughing (because once she gets a cough, it is nearly continuous, night and day, for WEEKS)
Teeth scraping on a fork
When someone stirs food in a pot with a fork, and it SCREECHES.
The screech of a fork or knife hitting a ceramic plate at the wrong angle. "SCREEEEEEEEEK"
When someone grinds their teeth
When someone does that Snorting the Boogers INTO their throat thing. "Grrrrruuuunnnnnnn"
Yes, I know lots of sounds "bother" me. DH always says my sense of hearing is crazy. I hear EVERYTHING. (And sense of smell...but that's for another day)
