I'm sure my older brother has figured it out by now, but then he dropped out of school junior year and I'm in college, so he really has no basis for complaining.

My little sister was somewhat disapproving until a few months ago, then she started smoking and drinking every so often (you know, an actual reasonable amount, something I've never been able to do), and so she is cool with it. Smoked with her a few times. We actually went to go see Snakes on a Plane together blitzed out of our minds.
