some people's breathing pisses me off.. and people talking slowly

i just get SO pissed and don't feel like talking with them at all anymore.
i had a golden retriever staying here (i took care of him now and then), he smacked his mouth, it drove me crazy!!! He like licked his paws very slowly and at the end of every smack his teeth clacked together, OMG i felt like killing the dog!
then of course mice gnawing stuff, and them running in the wheel, then stopping, running a little, stopping again.. and so on...
