Cross 'em off as we get them...
"AIBU to give my dc's just a shiny ha'penny and a handful of nuts for xmas?" followed by seasonal bunfight, during which at least four poster must list gifts worth over £1,000 for each dc. The words Mac Book Pro MUST be used. A similar number of posters will come on citing budgets of £2.21 including food, presents and decorations.
Minimum of two narcissistic DMs who throw a huge tantrums because family didn't guess exactly what expensive gifts they wanted for xmas.
The GPs who DARE to get their DCs a separate stocking/advent calendar/2nd present/ xmas pjs. This one will really kick off.
There will of course be the xmas pjs haters. This will also kick off. They will also take ombrage with icing sugared floors, hot chocolate in chests and all other new fangled xmas eve traditions, claiming they are NOT REAL TRADITIONS and JUST MADE UP. Staunchly the defending the xmas-pj position will be the xmas duvet cover owners, a group of militants you'd never actually meet in RL.
The cultish playmobil advent calendar openers who will check in daily to tell each other what new piece of plastic their dcs got today.
