One of the best tips for surviving the Christmas season is to exhibit the most exquisite manners to those you meet, and in particular to show good grace to those who offer you presents.
If for example somebody offers to pay you £50 billion a year and to let you fish for 80% of the stocks in their territorial waters, do not go off in a hissy fit just because they didn't agree to your pet money scheme. Bear in mind that they may not have the time or inclination to play with you all the time, and just be grateful what you do receive.
In fact, be mindful that all those temper tantrums do not go unnoticed, and all that foot stamping and talk of retribution simply marks you out as a nasty little person who will probably get less next year. And that nice Mr Wong from down the road might miss you off his Xmas list altogether.
