Mom: are you alright?
Mom: why are you smiling like that?
Kid: oh I was just thinking about this thing that happened, it was really funny, kyle fell, but he also fell and took down this old lady, but none of them were hurt, that wouldn't have been funny, that would have been really sad...(Etc.)
Mom: you're high.
Kid: no I'm not.
Mom: yes you are you got Stoney Face, just go watch cartoons.
