This is one of my biggest pet peeves when it comes to smoking. I seriously cannot understand people that leave the flame on the bowl for longer than a few seconds.

But even worse than people that do that are the people that light the bowl when its already cherried. Seriously, WTF?!??! Why would anyone even think of doing that? This guy I lived in the dorms with freshman year did that EVERY SINGLE TIME. I finally stopped smoking with him because it would be a buzzkill to see him do that. It bothered me that much. And nothing really ever bothers me enough to get furious.
