Mine is telling people you’re a good person while you’re not. Let them found out themselves. You don’t have to advertise yourself wrongly.

Chewing gum in a quite place, and making annoying sound with it. Like come on is quite for a reason. 

Chewing loud while eating and talking at the same time. Swallow the food already then talk.

Kids been bad and the mother purposely ignore the kids behavior to piss people off. Kid them on leash please. 

What is your pet peeve ?
