Zapfic50Friday Freewrite - Greet

Hello Sir! Happy holidays to you, I said to Mr. Peters, my chemistry lecturer. I know it wasn't my intention to greet him, It happened that I ran into him in the market while I was running errands for my mom.
I bet Mr. Peters didn't see it coming either.

This is my entry to @zapfic.club freewrite contest #zapFic50Friday with the prompt "Greet"
