ceilings

whose idea was it to put those little bumps on ceilings? why go to all the trouble of having to cover the rest of the room in plastic sheeting just to spray the bumpy crap up there? it seems really unnecessary. perhaps the purpose is so absentminded homeowners don't accidentally mistake the ceiling for the floor and start walking up there, or to make a more obvious differentiation between walls and ceiling, so people don't attempt to hang their family photos up there. that's all i can come up with.

wait. i just looked it up. apparently the bumps are intended to cut down on glare from lights or sunshine. interesting. now you know.
