Now my son is ten years old. At this age, the boy is interested in all kinds of things, and he's got more questions to trouble me. Do people in prison celebrate festivals? Why are dogs'noses always wet? Why are women and men's shoe sizes different?

Since my son was three years old, he's kept asking me "why?" about everything. Why is the sky blue? Why are there clouds? Why can't I go outside? Why do I have to be nice? Anyway, I always try my best to answer his questions.

These days, the boy shows interest in the facts of life, so I borrowed books from the library and prepared myself for any questions he might ask. At the end of our long talk, he still looked confused. "If you have any questions," I said, "please ask them. There are no stupid questions."

"Well. suppose I was married," he said with shame, "my wife was going to give birth to a baby, and I had to rush her to the hospital, okay?"

"Yes," I smiled and encouraged him to continue his question.

Then he asked, "Can go through red lights?"
