kissing machine

Today, while dishing out seconds of dinner for the boys I walked into our step stool - I didn't realize it was right in my path.  It hurt so bad and I got a nice bruise from it.  I complained about it for a bit.  We got back to dinner when Kekoa said, " Mom, I am going to invent a kissing machine."  "What?! What do you mean? What's a kissing machine?" I wondered where he could have gotten such an idea from.  "It's for kissing ow-ies," Kekoa replied in all his innocence.  Cute.
