Oooh, with a title like that, some people will be confused about this post's purpose. This is a puzzle.
There once was a man who saw heaven and hell, but found they were nearly the same. Each one consisted of a group of people sitting at a round table with food. But their chopsticks were way too long to eat with! The difference was that people in heaven were always full and happy, while the people in hell were always hungry and unhappy. Why?
This puzzle comes from Stories to Solve, which is the other book I found from my childhood. However, the book takes this story from an older tradition, so I don't feel I am stealing it. Some people might categorize this as a lateral thinking puzzle. I generally don't like lateral thinking puzzles, but I like this one.
