Getting hurt by things you love

I was walking up stairs as Zack yelled "ouch" and started rubbing his head. He was taking the guitar off and as he slipped the strap over his head he bumped heads with his guitar.

Later he came in a showed me a small welt. The first thing that came to my mind (and out my mouth) was "Zack, you always get hurt by things you love". I then showed him the scar on my forehead from when I was loading a computer in my car. I love the computer (though not as much as people).

He thought for a moment and then said "I never got hurt by the piano!". I asked, "Did you love the piano?" He responded sheepishly, "no". Then a light bulb went off and he said "Girls!! Basketball!!". I proudly said "See, I told you so."

Then I asked him if he's ever been hurt at the beach. He said yes.
