Most strips come from me hearing something, and finding it interesting enough to ponder. Even though it was over 15 years ago, reading this strip jogs the memory of my dad and brother having this conversation.
In fact, in the original version of this strip, the man on the right WAS Bruno’s brother. Upon revision, I decided that it worked best with her as an only child.
Is/was Bruno me? In ways, yes. I did not feel as dismissive of their thoughts as she does, but I believe I was the only one attending school at the time (although my dad was, and still is, working in the education system).
