'Tommy, aged five, pens his Christmas letter. His request? More brains for his family; they just don't understand him.
'He begs his mum to post the letter. With only one day left, it may not get there in time--he might end up with no presents.
'Or, he might end up with exactly what he requested.
'Santa Claus is coming. Be careful what you wish for.'
