The true meaning of Christmas

The holiday season is around the corner, so they have those mobile sales of seasonal items almost everywhere in Lisbon. In particular, there was a book fair close to the place I live, and, to my great astonishment, most books (which were, supposedly, the ultimate Christmas gifts) I've seen there could be divided into two categories:

• "A Primer on Practical Magic"
• "How to seduce somebody else's husband"
