I few years back I was the assistant manager at my karate studio. It was a slow, quiet day when in walked Paul, my old bully from public school. I wasn't sure at first - it had been a long time, and it was hard to tell.
I didn't say anything. Paul was interested in joining the dojo, and I showed him around, discussed pricing, etc. I didn't treat him any differently than I would any other potential client.
At the end of the tour, Paul decided to join our dojo. We sat down in the office and he filled out the paperwork. When he wrote his name out on the application, I knew for sure that this was, indeed, my old bully. The guy who used to torment me every single weekday. Who made me kneel in dog sh*t.
I still didn't say anything until after [he] pre-paid me for an entire year's membership. As I walked him to the door, I smiled.
"I'm really looking forward to training with you." I smiled.
"Thanks, me too," Paul said.
"You don't recognize me, do you?"
"No, should I?"
"Yes. We went to school together, Grade 3 through 8. You bullied me every day, and made my life miserable. Can't wait to see you in class."
Paul went white, and walked out without another word. And never walked back in. He willingly threw away a year's membership payment, almost $500, rather than have to be in the same class with me.
