~Laundry~
Knowing a human close up was still a novel experience. He watched, puzzled, as she piled clothes into the white box. Sweat trickled fascinatingly down her neck. He and his brothers didn't sweat as much, and they didn't have hair to curl and cling to their skin. He remembered the admonishment about asking personal questions and resisted the urge to ask if it tickled. Instead, he asked what she was doing, and was rewarded with a chance to help.
Later, he explained to his brothers that clothes, a uniquely human penchant, needed to be bathed regularly. The oldest feigned disinterest, but nodded thoughtfully. The Genius pondered a moment and explained, in great detail, about dust mites and some unpronounceable, invisible specks that populated human bodies. The warrior smirked and asked if he'd folded her panties, earning himself a reproachful glare and ten flips, since their father happened to overhear.
Grinning, he retreated to his room, to ponder this new information. She washed her clothes with a horror of dirt, yet visited them regularly in the sewer, without fear of the deadly ninja family. She was, he decided, a special kind of human, even if she did make him do laundry.
A/N: Once again, credit goes to Getting to Know You for inspiration for this one. April's early awkwardness with the Turtles was funny and sweet and is a lot of fun to read and write, but it doesn't take her long to recognize the "teenage boy" under the shell and start treating them like annoying-and-much-loved younger brothers.
