Love Hurts

During the holidays, we had the opportunity to watch my sister's kids for a couple of weeks while she and her husband went on a special vacation.
One of the best parts of that visit was this question from my 8-year-old nephew, Schuyler:
"Jo, what do people mean when they say 'love hurts'?"
Dare I say that I suspect my nephew has been exposed to some 80s rock? I certainly hope so...
