Every so often I'll be carrying my roleplaying books around with me in public, either as reading material or because I'm working on an adventure or something. And, every so often, someone will ask me, "Are you doing homework?"
Which is, I suppose, understandable. I'm carrying around what a couple of textbooks. They're textbooks about dragons, but they're still textbooks. I'm reading charts, and taking notes, and doing calculations. I look like I'm doing homework.
But I tell them, "No, no, this is fun. This is Dungeons & Dragons."
Which isn't entirely true. It is homework. It's self-imposed homework, it's fun homework, but it's still homework.
It's a weird hobby.
