I absolutely hate people who nag you.
Especially when they're nagging you to do things that you don't want to do, or know for a fact that you can't do. Sometimes even when you're already doing what they said, they're still sitting there rushing you saying "c'mon, let's go, c'mon, c'mon, c'mon!"
It drives me nuts. I hate repetition. It literally causes this tickle in the back of my skull and I'm forced to take a deep breathe or else I'll completely blow up at the person. Of course there are times when I can't control my anger and frustration and I end up screaming my head off until that person gets the hint to leave me the hell alone.
Parents and teachers are the best at nagging you. Whether it's something as simple as getting out of bed in the morning, or even getting a project done, they nag you. I can't stand it. It's like a pet-peeve multiplied by infinity.
If you're someone who nags,
Don't talk to me.
