"I learned it from you, okay, Dad?!? I learned it by watching you!!"
I don't know what's worse, the fact that you died from a heroin overdose, or the fact that it was so easy to get the heroin because your dad brought it into your place of residence, and when he found out what you'd done with it, he beat you for it like it was your fault even though he was the one who made it so easy for you to get.
