When my sister and I were little, our Dad would challenge us with riddles and word games. I mentioned three in my eulogy for Dad:
1. Imagine a two-volume dictionary sitting on a shelf. Each volume has 500 pages. A bookworm is on the first page of letter A. It wants to eat its way to the end of letter Z as fast as possible. How many pages does it need to eat?
2. Should you walk to work or bring your lunch?
3. Is it warmer in the summer or in England?
Dad used the first to show the perils of leaping to conclusions. The second introduced basic economics. As far as I can tell, the third is just amusing; if you see a deeper meaning, please let me know.
