I'll usually let alot of stuff slide but some things just grind my gears
People with bad breath, B.O., or your home smells
Close talkers, seriously you need to take 3 steps back before I punch you in the throat
Leaving barely any coffee in the pot so the next person has to replenish it
Parking all fucked up on the street or parking lot
Being late for anything
Firing up your snowblower at 11pm at night
Not flushing the toilet and people that don't wash their hands
