One has to ask, which came first? the chicken or the egg.
The bad parental behaviour or the flaky behaviour of the teen?
It seems pretty obvious here that the parents have violent tendencies.
Flaky inappropriate "look at me" behaviour is often a cry for help,
violence and/or abuse is often a factor in troubled children.
Bring on the legislation for a vetted "parenting license" I say!
Too many abusive rotten parents in this world.
Would you be a troubled child sir seeking help from some public message forum?
