Ah, the "What the fuck are you on?!" look -I'm very familiar with that look. If I happen to be watching SPN (which, for some reason, can make me sob every damn season -at least twice- nothing else reduces me to tears like that I swear), it's usually accompanied by the "Oh, god, she's really insane" walking backwards; which happens about the time I start sobbing about they love each other and they can't be complete alone... It's really quite sad, now that I think of it...
