How to put this…
Maybe we should just start with the punch line. “Petra? I thought your name was Iva.” “No, that’s my mom.” It took a couple more times back and forth before I realized: There’s two of them. That explained a thing or two (a rather inconsistent level of happiness to see me, for instance), and it meant I got really lucky earlier complimenting Petra on her haircut.
Hilarity preceded, only now I got the jokes. I sat at my table as Petra’s birthday party went on around me, and laughed to myself, wondering how long it would be before someone else figured out my mistake.
