Great thread! I have a loong list of pet peeves.
People who comment about what's on my plate. (I'm a vegetarian.)
People who park in parking spots intended for expectant moms or parents with little ones
Don't even get me started!
People who drive slow in the passing lane
Hearing the phrase "I don't know how you do it" in reference to being a single parent. I don't know why, this should be something I appreciate but for some reason it isn't. It makes me feel pitied, or like people don't think I have a nice life.
All the 'throw away' stuff in our society. Disposable diapers, cuttlery, 'take out' containers, plastic cups, wipes, and many other things used on a daily basis... just picture a year's worth of all of that sitting in a landfill for eternity because that's literally what's happening.
Poor grammar/spelling.
Slow walkers
People who take the elevator to the 2nd floor (when there are stairs.)
Really loud sneezes
People who play music loudly. I don't want to be forced to listen to music I don't like lol
People who text/stare at phones when they are in company of family/friends
