Calvin and Hobbes by Bill Watterson for July 12, 1993
Calvin: Gorgeous morning, huh dad? Dad: Mm. Calvin: These summer days sure slip by, don't they? Too bad the daily drudgery of making a living has to keep you from appreciating these sublime moments of life. Well, best not to think about it! If you stay healthy, you can enjoy days like this when you retire! See you tonight! Ahhhh, summer!
