From today's Daily Telegraph:

If you can't be bothered to read it all, the child was invited to, and accepted, schoolmate's birthday party - a dry ski outing.
But something else came up for invitee's family, involving grandparents, so the child didn't go to the party and somehow the parents couldn't (they claim) inform the birthday child's parents.
Result: in the no-show child's school bag, an invoice for the cost of the place at the dry ski that the child didn't go to (fifteen quid and change). Now escalated into threats of Small Claims Court! No show child's family say they had no contact details to say child was not attending ... birthday child's parents say oh yes they did ..... discuss!
