Good luck with the monster, good luck with the oranges

We were both going the wrong way down the same pavement in Roma Norte on Saturday, you with a canvas tote full of oranges and me carrying a very large plant I had just bought. We met in the middle and did the thing where both people go left, then both go right, three times. You said, good luck with the monster. I said, good luck with the oranges. It was the best conversation of my week. The monster is fine. I ate an orange in your honour.
