Is it normal that my neighbor's child acts like this?
I have lived near these neighbors for over 10 years. Around 2 or 3 years ago, their little girl (now 5 years old) started to play outside with others. First, I did not mind her. But then I met her and interacted with her. I will list her aberrations below.
1) She is rebellious, she goes as far as saying "You're not the boss of me!" to her own parents. She doesn't listen to older kids either. She'll just hurt them. (Below)
2) She is somewhat harmful. I do not know where she got those muscles, she looks like a normal 5 year old girl. She enjoys, hitting, biting, spitting at, pinching, punching, slapping, stomping on, pushing, and kicking older kids (mostly boys 10+), WITH GREAT FORCE. And for no reason whatsoever. She has bruised me and some friends dozens of times and even caused bleeding once.
3) She can be EXTREMELY moody. If you do not give her 300% of everything she wants, she will go on an hour-long temper tantrum. I hear it daily and I live three houses down. Afterwards, she will run very far down the street and hide in a corner or behind something, physically injuring anyone who comes within 10 feet. Usually, she won't come back for up to 2 hours.
4) Threats. She has told me this (just last week) (exact quote): "I'm going to break all the bones in your feets with big huge rocks." And the tone of her voice was EVIL. EVIL!! After hearing this, I was stunned to hear such words coming out of her mouth. I had a talk with her parents immediately.
One last thing, she is more spoiled than... I don't even know.
