To the extent that u feel like throwing a chair at the person and killing him on the spot.
criticisms:
For me, I guess I take it very personally when people criticize me about my appearance (if it ever happened).

I also hate people who criticized about my family and friends infront of me or spread malicious rumors about them, even though it seems to be none of my business (in a way). I also can't stand people who said that I'm boring, and I will go all way out to defend myself. Luckily, it only occured once, when a female ESTp who didn't know me well said that.
pet peeves:
-people who criticize others too much when they are not perfect themselves.
-a messy bedroom.
-people who take life too easily.
-people who walked past me smoking and blowing the smoke into my face.
-a life without a sense of purpose, living each day not knowing what u r here for.
-people who follow fashion and trends blindly.
-not having much money to buy things I want.
-guys who are good-looking but not intelligent. Bores me to death when I talk to them.
That's all I can think of right now.
