Every night before bed, Steve and Ian read Calvin and Hobbes. It's Steve's old edition from when he was a kid.
Watterson, who is apparently a big recluse, just gave an interview. When asked why he chose to end the strip when it was still really popular, he said,
By the end of 10 years, I'd said pretty much everything I had come there to say.
It's always better to leave the party early. If I had rolled along
with the strip's popularity and repeated myself for another five, 10 or
20 years, the people now "grieving" for "Calvin and Hobbes" would be
wishing me dead and cursing newspapers for running tedious, ancient
strips like mine instead of acquiring fresher, livelier talent. And I'd
be agreeing with them.
I think some of the reason "Calvin and Hobbes" still finds an audience today is because I chose not to run the wheels off it.
I've never regretted stopping when I did.
