Kristin -- no matter how much you hate her, she's always fun to hang out with.

Everyone has that friend who's every day, like, 'I hate my nose, I hate my nose, I hate my nose.' You either need to come to peace with it and be like, alright, I hate it, but it's part of me - or change it. So I'm not against plastic surgery, I'm against plastic surgery when it doesn't really need to be done.

When you're growing up, you play dress-up - it's a game, it's a pastime. And then as you get older, getting ready and looking nice becomes this constant stress. I want to make it fun again.

I hate to subject it to too much analysis, but one thing I have fun with is the rarity of things being shown from an adult's perspective. When Hobbes is a stuffed toy in one panel and alive in the next, I'm juxtaposing the "grown-up" version of reality with Calvin's version, and inviting the reader to decide which is truer. Most of the time, the strip is drawn simply from Calvin's perspective, and Hobbes is as real as anyone.

Time flies when you're having fun, and I've been having fun for the last 30 years.

Love unrequited is violent. He loves you so much that he's turned it into hate.
