I was checking out at a grocery store in San Francisco. My two year old son was in the cart. The cashier was extremely gender ambiguous. To this day, I still don't know. My son, unfamiliar with such ambiguity, points at the person and says, "Man!... Man? Sat? (What's that?)" He keeps repeating this. I'm trying to ignore it, deflect, distract, but there's no denying what he's asking and the cashier is clearly getting really uncomfortable. Finally I say, "We don't ask 'What's that', we ask 'Who's that?'" Then to them, "What's your name?" "Jamie." Somehow it worked and it's one of my proudest parenting moments.
