I think you got the parent/child relationship dynamic all wrong. Are you seriously going to hold an ansgty prepubescent teen accountable for her hormone-raging thoughts? It was an outlet for her, which apparently she didn't feel she had any other outlet (parents' fault if the kid won't talk to you).

My dad used to do dumb shit like that. He'd buy you something, then if you were disobedient, he'd destroy it in front of you. Well guess what, you bought and paid for it, numbnuts. Doesn't help anything. He could have at least re-purposed the laptop or given it to charity. Instead he gets to have his little temper tantrum and post it to show his power over his kid instead of dealing with it like an adult.

Best part is, when this guy is elderly in about 20 years, his daughter won't be around to wipe his ass. What goes around, comes around, bad parents.
