A 16 year old girl/land-whale at a bus station was running around her older brother playing with a ventolin puffer spraying it on his arm and trying to give him a frosty.
him: Hey don't waste that.
her: I can't waste it *spray* it's only air.
him: No, it's a drug.
her: *shows him the label* see it's air!
him: No it's a drug called ventolin it opens the up the lungs when you find it difficult to breathe.
her: No it injects air straight into the lungs and breathes for you.
him: ...Then why do you have to breathe it in?
her: So you get more air!
him: ...Stay in school.
