That can't be right

Conversation at the MacFuddle house:

Boy 2 (trying to get out of going to school):  Why can't I be homeschooled?
Me:  I just don't think I'd be a very good teacher.
Boy 2:  You'd be my teacher???
Me: Yes, that's where your plan falls apart.
Boy 2:  Oh.

I suspect he won't ask again.
