yea man i hate those kind of people, although i do think that if you're going round to someone elses house you should tell them if you're gonna smoke. Their parents might be in, girlfriend etc and they might not like it.

These days ive been smoking by myself a lot, because other people never want to get high except for parties which i prefer to drink at anyway. ( if im high at parties i usually just sit back somewhere, but if im drunk i will be up around dancing, whatever)
