The North Pole
Dear Alex,
Happy birthday! I keep two lists at the North Pole. One is the famous one. The other is a calendar of birthdays, and yours came up this morning with a note beside it that simply said: write to them.
A birthday is your own personal Christmas. Nobody else gets this day. I hope there is cake, I hope somebody sings badly, and I hope you get at least one present that makes you laugh out loud.
Have a marvellous year of being your new age, Alex. I shall see you in December as usual.
Many happy returns,
Santa Claus
