My biggest pet peeve has something to do with motorists. You know when you feel like going out for a walk on a rainy day and you're walking down the street listening to some music and, out of nowhere, you spot a car swerving into a puddle on purpose just too see you get soaked? Can you relate?
Unfortunally, this has happened to me more than once. I think such motorists should get a fine for doing something like that. Then again, some motorists go through standing water unitentionally. The best thing to do in order to avoid getting splashed by a vehicle is to walk far from puddles, I guess. Surely I have a lot more pet peeves, but this was the one that popped into my mind.
