Calvin and Hobbes by Bill Watterson for March 17, 1994
Hobbes: What a busy day! I'm pooped! Calvin: Mom says the roads are pretty clear, so school will probably open again tomorrow. Now I wish I'd done my math homework instead of playing outside all day...or I wish I'd done it before dinner...or after dinner...or instead of watching TV...or before bed. But now it's too late. A day can really slip by when you're deliberately avoiding what you're supposed to do.
