“Sutton and Bennett’s dad?  Hi.  We had a little biting incident today.”

“Oh no!  What happened?”

“Well, Sutton bit Bennett.  They were just playing around, but then she asked him to bite her back, and he broke the skin.”

“Oh, whew!  So they only hurt each other, not anyone else’s kid?”

“Oh yes.  They’ve never hurt the other kids, though Sutton has a habit of tackling all the boys and kissing them.”

“Great, so I have nothing to worry about then.”
