Now that's just weird

A mother that I barely know -- as in I've spoken to her four times in two years -- just asked whether I would bring her child home with Abigail from school on Mondays. I understand being worried about how to handle working and picking a child up from school, but our school has an after care program. Whyyyy would you ask someone you don't know well to take your child home? Especially since she was just asking for once in a while when her family couldn't help out? I find that very, very strange.
