A 5-year-old boy was given an invoice from a classmate’s mother after he failed to show up to the classmate’s birthday party.

Derek Nash said his son Alex was confirmed to attend a birthday party at a dry ski slope when he realized Alex was double-booked and scheduled to spend time with his grandmother, the BBC reports. Nash said he didn’t have the contact information of Julie Lawrence, the classmate’s mother, and later found the £15.95 invoice (about $24) in his son’s book bag.

“I can understand that she’s upset about losing money,” Nash says. “The money isn’t the issue, it’s the way she went about trying to get the money from me.” Nash said he has been threatened with small-claims court if he does not pay.

“All details were on the party invite,” Lawrence said in a statement to the BBC. “They had every detail needed to contact me.”
