It's one of life's mysteries that will never be solved and will leave people stumped for years to come.
Why do families argue on the most joyful day of the year – Christmas?
In my family five things are guaranteed to be happening on December 25th:
1. Someone wont be talking to another member of the Rosenberg clan.
2. My nana and granddad will bicker over whose place of residence it better - Liverpool or Suffolk.
3. My uncle will get hammered and fall asleep.
4. The boys will cheat in whatever game we play which is invariably Pictionary or charades.
5. After one to many rose spritzers I'll offend someone or reveal something I have been sworn to secrecy over.
It will happen this year, just like it does every year, but for some reason the arguments continue to baffle me more than anything.
Last year was probably my favourite spat as bizarrely, my dad didn't talk to my mum for two hours because she forgot to cook potato croquettes as part of the Christmas dinner, which for some unknown reason is a staple to our festive roast. Odd, I know.
In years gone by, my cousins and I would argue about who was going to perform Backstreet Boys' songs in front of the rest of the family (I was never allowed, yes of course I'm bitter).
I don't know if it's the pressure of the day and everyone wanting it to be perfect or just the chaos caused by the entire family getting together.
At least in my family we don't argue about whether or not to watch the Queens speech (we don't), unlike some friends I know. And I certainly don't argue with my boyfriend for not getting me a present when we had agreed not to buy gifts - mainly because he's not stupid enough to get out of bed without a gift on Christmas Day.
Now I like a good tiff - I'm a feisty redhead Gemini so it's kind of written in the stars - but this Christmas I would quite like a rest from the annual bickering. Let's all just get pissed on champers and Baileys and be nice. Quite literally have a Merry Christmas.
