Wall of Happiness

Once upon a time, there was a poor man, a middle-class man, and a rich man. They were all talking about how they found happiness in their lives. The rich man said, "I found happiness through money and all of my assets." The middle-class man said, "I found happiness through my steady job and my loving household." The poor man said, "I may not have much, but I find my happiness through the little acts of kindness people show me."

And then the wall fell on them.
