And it wasn't so much staring as watching her stalk by; she didn't look too happy, and so he was thinking of a careful greeting that wouldn't invite any anger - because sometimes, his mouth talks before his brain can filter it and that'd be bad.

But also she's pretty so maybe it was a little bit of staring. Don't judge him, okay.
