Him: Can you help me out at the festival tonight? We'll be setting up starting at about 3:00.
Me: I'm really sorry! I'm taking a driving course, and I won't get back until 8:30.
Him: OK, never mind, then.
I spent the rest of the day thinking, "Dammit, I could be teaching go at the festival! That would be so much fun!"
I got to the festival just as it was wrapping up, and there were only a few vendors left. Of course, I lined up for takoyaki, and plenty of my students stopped to say hello. I asked a few of them if they saw an old man who was teaching go, but none of them had.
Finally, I spotted him-- or rather, he spotted me-- while I was in line for a crepe. He was selling grilled squid.
Me: What's going on? Weren't you going to teach go?
Him: No, I was going to sell grilled squid! If you had some time, I thought you might help out.
Me: Not to sell grilled squid!
Him: Hey, that's a pretty good idea. We should teach go at this festival next year!
