More than two billion people celebrate Christmas globally every year, and it seems that there are as many Christmas traditions as there are countries around the world. Did you know that in Serbia, for example, the children have a tradition of tying up their parents? Two Sundays before 25 December, the children tie up their mum and she then has to pay a ransom in the form of gifts to be freed. The following Sunday the same happens with dad. I guess that's one way of getting what you want for Christmas... In many other countries, the good children do receive presents, but awful things can happen to those who have been naughty – a stick, a lump of coal or even a visit from a witch!
