Oh god, that's why I can't stand most kids... they are so petty and arrogant. The #1 reason for that is that parents can't say no to their children. They are like "I dont want to break my little kid's heart". But what they don't realize is that if they don't give their children limits society will do... and it will be a lot worse.
I'm saying that because I stayed at my aunt's house for 4 months this year and she was like that. Her boy (was a nice boy though) wouldn't eat anything but burgers, food with justice league labels, and coke. He could get very petty some times, specially when he missed his fucking cartoons (which aired every fucking day anyways). He really pissed me off once.
It was mother's day, we went out to have lunch and when we came back home he realized he had missed his fucking cartoons and begun to yell at his mum saying shit like "you don't love me, I hate you now, I'll leave this house etc..." And man, he's only 6...
