well, steve, i see your point and i've suffered too because of the stern discipline imposed unto me by my father when i was younger.
the only words of comfort i have for you are: you'll grow older, make money, move out, and be free. it's not like your time is running out now. no matter what you believe at the moment, one can still enjoy metal shows at 25 and later.

so - i even think, as i believe i stated before on this forum, that it's correct to be forced to follow other people's rules when you don't earn your keep - it shows you, albeit roughly, that there's no free meals, and you'll more probably grow up to be a person who can tolerate pain better than those who've been mollycoddled (no offense towards anyone who's had or currently has tolerant, enlightened parents: i actually mean to be one when i'll have the chance). in short, look at the bright side, even though it's hard to see one now. i reckon that there is superstition in what is keeping you from shows, but this will make you fight harder, study harder to get a good job soon and move out, concentrate harder on what you want.
