I completely 100% agree with you. It's stupid and irresponsible and these people don't realize what kind of effect they're having on their lives. It may not be a big deal right now, but they're totally risking their futures and losing or at least disappointing and disgusting smart friends who have to sit back and watch as it's happening, and no matter what they say, there doesn't seem to be anything they can do about it.
Good blog entry.
