I have a low tolerance for people who leave trash where ever they go. Nothing like going to a picnic or camp and finding that the last visitors left a truck full of trash. I also dislike those who mistreat animals. if you can't treat an animal right, you may not be good at treating people well either.

Watch this video and you be sure to read the seal on the floor in the dance scene, you'll have a weird understanding of things after seeing it.

I too have low tolerance for people who are mean to children, ESPECIALLY BABIES! When babies grow up in those environments, it makes them bad people. Hurt people hurt people. There are people who simply should not breed. And I'm the same way about mistreating waitstaff and service personnel. Maybe because I've working in service industry all my life. But my biggest pet peeve is probably ignorance, which leads to these horrible behaviors and more. Just ignorance. It breads fear which breads hate.

I would have reported the mother. That is abuse and unlikely to end there.

A pet peeve of mine is people who use quote marks with their fingers. WTF is that about?

Another one is drama of any kind for no apparent reason.

Litterers. Pretentiousness. The phrase “have a blessed day.” Peanut butter in the jelly jar. Trumpsters.

Bragging people. People who go out of their way to tell you how great they are, what cool stuff they have, what awesome things they do, the insane places they go to, the people they hang around with. Man, what do you have to prove?!

I'm with you on the kids, it really fucking pisses me off. I have actually given people the hard stare or have said something to them. I want to I hate it when people that have kids, try to tell me how to raise my kids, I just tell them to get the fuck out of my face, with that B.S. I also hate men, that hit women.

Rubberneckers...they back up traffic sometimes for miles, creating hazards, plus, ya seen one dead body/crushed car, you've seen them all, drive on, you fatheads.
Also, those who do not know how to merge. I am Done slowing to let you in!

People who take their food out of the microwave and leave cooking time remaining on the clock.

People who think Envy and Jealousy are the same thing and use the words interchangeably, like wise people who don't understand Lend and Borrow are antonyms not synonyms.

People who holler at clerks in store for something they didn't do just to make themselves feel powerful

Littering.

Dog owners who leave dog poop in plastic bags broiling in the sun beside the trail. What, they think the Poop Fairy will magically clean up after them?

Dog owners who refuse to train or control their dogs.

Today a woman brought her small dog into Macy's.The dog pooped on the carpet in front of the main checkstand. Disgusting. Leave your dog home!

I have one and my Mother would always get pissed off at my Father when she asked him either what do you want to do or would you like to go here or there and He would always say i don,t care or which ever you want but would never make a choice ,I tell people right up front if i give you a choice of going here or there,do not say i do not care,,Since i have given you a choice of either means I am ok with either,I am giving you the courtesy of picking which one you like best and if you happen not to like either one,then come back with another suggestion .Please that is my pet peeve
