It had been a long day at the lab. I had been struggling with my research, and I just could not figure out why I wasn’t getting it to work. I was tired and it was late. To make matters worse, the sky was dark when I finally left. As I was walking home, I reached a stoplight. I reached out into the darkness to touch the crossing button and instead felt something squishy.

“AH!” it shouted.

“Sorry!” I screamed. “I didn’t see you!”

I had poked a man in his stomach by accident.

I laughed the rest of the way home.
