Christopher explains Santa

Christopher saw an advert where a little girl makes (brand name) cookies for Santa and she says "If we give him these cookies we'll get lots of presents."
"It doesn't work like that." he said. "It's whether you're good or bad."
"If you're bad and you make Santa lots of cookies, you won't get what you ask for, you'll get educational things."
He looked at me, then said:
"Educational things aren't bad though."
