What was she thinking?

I agree with dodge. Buy a new hook and eye type latch you can put up out of reach and then photocopy the bill and hand it to the mom with a comment like your "lesson" the other day will cost you one new latch to put at the top of the gate or your child will no longer be safe at my house. IF she pays it fine but I would let it go after that in the sense that you got your point across.
