Stepped on a foot

When I stepped on the principal’s foot, I still did not know that it was the principal.
He said, “So you stepped on the principal’s foot!”
I did not say anything, but my breath was heavy. I did not know what to say.
“So, why aren’t you answering?” asked the principal, “you don’t have anything to say?”
I nodded.
“Hmm, look at him,” said the outraged principal, “stepped on the principal’s foot and is nodding like he is proud of what he has done.”
I shook my head.
“No, just look at him!” said the mad as fire principal. Shaking his head like nothing had happened. Like it’s not him who stepped on the principal’s foot. Do you know what I can do to you?”
I nodded.
“Do you know? Are you interested?”
“You can also step on my foot,” I said suddenly, “And then we won’t be in a fight!”
The principal thought for a moment and gently stepped on my foot. And we weren’t in a fight.
