IMAGINE . . .
Leah spots you at the bonfire one night. Jacob had had the nerve to bring you - a friend of those bloodsuckers known as the Cullens - along with the girl he idiotically fawned over, Bella Swan.
Though she hates to admit to herself, for a vampire sympathizer, you're definitely pretty, and the light of the fire illuminating your face just makes you look so ethereal and -
Your eyes suddenly glance in her direction, locking with her's. Leah freezes, knowing she's been caught out staring at you like a moron, so, dying with embarrassment and a serious hit to her ego, she turns on her heel and marches away.
She could feel her face burning the whole night from the humiliation of being caught admiring you.
