The incident reportedly happened last November at the Allenton Community Primary School in Derby, England, though the boy’s parents just recently learned about the encounter between their son and his instructors when he brought home a poster and recounted it to them, The Guardian reports.

“[My son] approached his behavior mentor and said he was being bullied and was upset the other children didn’t like him. So, to try to tackle this, his [behavior mentor’s] idea was apparently to find out why the other children didn’t like him. So he sat [my son] down, asked the other children why they didn’t like him, and tried to tell [my son] to change those things,” the 10-year-old’s father Damian Lightoller told the newspaper.
