Mexican kids are so lucky. Not only does Santa visit on Christmas Day, but on January the 6th they get more gifts from the Three Kings. They have to write a letter to them, telling them how good they have been, before attaching it to a balloon and releasing it to fly high, higher, higher still….till it disappears entirely. At that point mum or dad can tell their little angel that at least one of the kings has it and is reading the note with great interest. It does also, of course, provide another seasonal employment opportunity for the street vendors of the city….
