At first, I thought he had stepped on a frog, but then I realized, thanks to a windy day, that he had let one rip. You can't see the wind, but you can feel it, and now it had another characteristic I discovered. You could smell it. He seemed like a nice enough fella, but just the same, I was a wee bit asthmatic, so I put on my hat, buttoned up my coat, made up an excuse, and I politely walked away.
