DOING THE MATHOk, so Santa Claus asks "Have you been a good girl this year?", "-yes" you say (no matter what).Technically, there's a week Santa is not counting. You see, he leaves our presents on the 25th, and the year ends on the 31rst. Then next year, he asks again "(...) this year?"... Santa is not counting those 6 days after Christmas, meaning that, we're legally allowed to misbehave for a week and still get presents next year without being questioned by Santa (or anyone) about it.
