i cannot buy glass, I have this weird disease that somehow causes me to lose a grip on any glass pipe and somehow find a way to drop it on the hardest thing in the room. Fully carpeted living room, drop my bong on the granite coffee table, in the basement, floor covered in rugs, drop my pipe on the only exposed cement in the place. Tapping out my pipe into my hand, whole bowl breaks and pops out. gently using a wooden dowel to clean some resin, pipe cracks in half. Hell one time I blew into the pipe to clear it and the bowl piece just flew out. Im cursed to use Bullets, Proto Pipes, Joints and hitters. I won't even touch someone elses glass either as i have broken one of my friends pipes already by dropping it on the couch cushion. Good thick glass pipes is what i use to buy, but it doesn't make any difference I break them all.
