Absolutely, I just meant that there is never any one hard and fast answer to any question of RP etiquette. It'll always differ based on the people you're with.
Mostly there are just sets of "best practices" for general open RP, but that might be verging into discussions of semantics. Anyway, the biggest detriment to the vast majority of roleplay I experience in WoW is people being overly concerned with what they (and others) can and can't do, rather than treating it as something contextual.
