"...Most of us get old without growing up"

Bill Watterson:

Calvin is autobiographical in the sense that he thinks about the same issues that I do, but in this, Calvin reflects my adulthood more than my childhood. Many of Calvin's struggles are metaphors for my own. I suspect that most of us get old without growing up, and that inside every adult (sometimes not very far inside) is a bratty kid who wants everything his own way. I use Calvin as an outlet for my immaturity, as a way to keep myself curious about the natural world, as a way to ridicule my own obsessions, and as a way to comment on human nature. I wouldn't want Calvin in my house, but on paper, he helps me sort through my life and understand it.
