consider all possible ramifications of your actions.
if you leave w/o your dads permission then you can be called in as a runaway and any house they find you in, the owners could be charged with harboring a runaway (you) and they could get in bg trouble for it.
not trying to be a buzzkill, but if you want some of my advice im going to need a little more info.
how old are you and what state do you live in?
you sound like you might be 14-15-16 years old(?)
