Tina was one of those “special” kids.
Looked totally normal from the outside. No limp or big forehead, or tubes sticking out of her. Okay, maybe going everywhere with her Betsy Wetsy was a bit off.
She was just kinda slow.
Her parents tried hard to “mainstream” her with routines and chores: clean her room, vacuum the floors, do the dishes. That kind of thing.
When her dolly got messy from being dragged in the mud, she could run her through the dishwasher herself.
As for the kids she was supposed to be babysitting, that’s for a jury to decide.
