As I left the grocery store, I noticed two little kids, maybe six or seven years old, selling candy bars in front of the store to raise money for their school band.

"I'll buy a chocolate bar on one condition," I said to the boys. "You eat it for me."

I bought one and handed the candy back to one of the boys.

He shook his head. "I can't," he said.

"Why not?"

Looking me in the eye, he responded gravely, "I'm not supposed to take candy from strangers."
