Mona Lisa Smile
“You smile like you know something that other people don’t.”
It was supposed to be an insult; he could tell by the derisive tone in the girl’s voice as she haughtily stared down her roommate, sizing her up from a vantage point inches below her target’s own line of sight, yet puffing her chest out like a hen and popping a hip to shrink even further towards the earth. The girl in question looked on with as much nonchalance as he had ever seen a woman react to a personal attack, as though the first had never said anything at all.
Then she smiled. “Yeah, I guess I do.” Lips curling wide, teeth flashing, eyes crinkling with silent, private amusement. Mona Lisa held fewer mysteries behind her gaze.
What exactly she was affirming with her words, he would never know.

Heya,
That was good. ^^ The description of the offending one was quite nice, specially with the hen and hip references. I had never looked at it that way, so now the next time I see a woman in that attitude, I don’t know if I’ll be able to not laugh. ^_~
Keep it up,
