Photograph the presents you have bought/make a list of gifts to refer back to in case of The TWITCH.
Hold off for the last minute pre christmas sales before buying expensive electrical stuff
ALWAYS eat out on Xmas day
Always have a spare present or five, just in case! Chocs/cars/dollies/craft things cover most people!
Don't ever rely on ex knobhead to buy Santa's main gift again. He will hold it hostage at his house so that HE gets the credit for buying it
meaning you have an Xmas Eve panic and have to rush out to duplicate the gift so DS has his main present to open on Xmas morning.
Buy gift wrap/new decorations in sales.
Buy gifts in sales throughout the year.
Make a text message/calendar reminder note of any gift ideas/hints you get from people through the year.
