you were a guy/girl/person who mostly caused trouble around your household, and school. your mother didn't know what to do with you anymore, and she didn't want to let you alone at home while she was working, so, she engaged a babysitter, Red.

he was almost the same age, since he was 18 and you were 16.

he was talking with your mother politely before she left. "yes, dont worry, I've dealt a lot with brats." he glanced at you coldly.
