"Uhm," Serena raised a finger to her chin, and she turned her gaze down to where her toes met on the floor. It was a weird question, but kind of a hard one. "I think, from the bottom?" She looked up at him, letting her hand fall away from her chin. "I don't usually think about it. I just," she held up her other hand as if she were holding a toothbrush in it, and mimicked squeezing a toothpaste tube with the other. "Squeeze some out and brush my teeth."

Her hands settle back down to her lap, and she blinked curiously over at Herc, wondering if it was a good enough answer.
