sounds like your dad's the type to lecture about pot and abuse the fuck out of you, and drink a 12 pack afterwords thinking he's the man for punishing his child with his fists (...and a remote) for doing "drugs"

get the fuck out of that house for your own sake. and press charges on the prick for everyone else's sake. don't get me wrong, punishment isn't a bad thing, sometimes it's nessecary, but BEATING YOUR KID is the lowest shite imaginable.
