People with no common sense.

Drivers who pull out in front of your and go sooooo sloooooow.

Fake people who act like they don't know you, then find out who you're related to/friends with, and all of a sudden, you're the best friend.

People who complain, nag, whine.

Ones who are intolerant of others' religious views, lifestyle, philosophies...LIVE AND LET LIVE!
