Conversation on a Train

A young boy sat on a rough cushion, staring out the window at the rolling hills.

Sitting across from him was a middle-aged man in glasses with circular frames.

The man said, "Some quick advice, that I wish I had when I was your age. Do not listen to those who do not follow their own words. I still have trouble with this one."

The boy was trying to picture what the man would look like without the glasses, but he coulnd't see it. So he said, "Ok," and went back to staring at the landscape.

It was very green. The man looked over his shoulder to see what had been keeping the boy's attention.
