“You look like you’re saving the world. Are you saving the world?”

I looked up from my notebook into the face of a tipsy, friendly woman, glammed up for her night out. We were in the narrow aisle of our local pizza joint. She’d shared a quick snack with her friend, and my sandwich and soda were half-finished. Writing here has become a Friday night tradition: When I wrap up my shift at the bookstore, I head here to eat, read and sketch out last-minute ideas for my reading lists.

If she knew what I was reading, she wouldn’t ask me that. “No!” I laughed. “I wish.”

“Well, good luck with it, whatever you’re doing,” she said. I thanked her. She left with her friend.

I was reading—am reading—about guns. About their magnetism, their effect, their handlers. About the people caught in the literal crossfire, the innocent and the marginalized.
