Character Analysis
This lady seems nosy—even though she's doing the completely right and logical thing.
When Kevin shops for groceries all by himself, the checkout girl grows suspicious. Kevin swats away her questions—which, when you think about it, are really just responsible sounding. Check it out:
CHECKOUT GIRL: Are you here all by yourself?
KEVIN: Ma'am, I'm eight years old. You think I would be here alone? I don't think so.
Owned.
Then, still suspicious, she asks him where he lives, and he says,
KEVIN: I can't tell you that.
CHECKOUT GIRL: Why?
With the verbal equivalent of a Mortal Kombat finishing move, Kevin replies,
KEVIN: Because you're a stranger.
Owned again.
Even though she was trying to help and be socially responsible by looking after an abandoned kid, now she looks like the weirdo. You have to feel a little bad for her.
