You shouldn't always smile for the camera.

Sarah Fowlkes, a married 27-year-old science teacher at Lockhart High School, in Lockhart, Tex., has been arrested and suspended from her job amidst accusations she had sex with a student.

Yeah, stories like that are a dime a dozen these days, but what's different about this case is the mug shot. Fowkles is beaming like she's sitting down for her photo in the yearbook instead of a picture that's followed by a cop yelling, "Turn to your side!" Seriously, she looks so thrilled, like she's remembering the more pleasant aspects of the alleged romp that got her into this mess in the first place.

Fowlkes could use this photo on Tinder. Seriously, who in their right mind would grin so broadly in a mug shot? Someone who's in hot water for doing the nasty with a student, that's who. Otherwise, when you've been hauled downtown for a crime -- any crime -- your facial expression should show no more pleasure than the ones in American Gothic.
