I still find this funny several days later, so I thought I'd share...
When my friend and I were in Boston with our kids, we all got ice cream. She handed a cone to her son and said, "Okay, David, now, use two hands and lick gently."
I realized that there were certain other circumstances in my life where similar advice might apply, and I was amused. Life just changes in all sorts of ways when you're a parent.
