I have this mostly when I have PMS. The cat licking itself drives me insane! Or my son smacking his gum in my ear while looking over my shoulder at the computer. STOP!
One that really gets me and that I feel bad about is the sound of someone searching for something. My ex would spend HOURS looking for a lost pill that he somehow convinced himself that he lost. Now, I can NOT handle the sound of someone searching for something. The rustling and all that will send me over the edge!
