When I was 3, my father's mother bought me a Scaletrix set - this was during the late 70's, so nothing like the ones that exist today, but for the time, it was highly exciting! We were staying with my mother's side of the family that year (the last time we did so, actually), and my older brother (13 at the time) threw a wobbly because he'd not been given my gift. My parents spent most of the morning explaining to him that (a) my grandmother was not his grandmother, (b) he had other gifts from her, which she didn't "have to give" him, and (c) it had two controls, so I'd undoubtedly let him play with it, too. The afternoon was spent with me sobbing on my great-grandfather's lap because my brother had taken it upon himself to set up my gift and wouldn't let me play with it - aided and abetted by my father, who wanted a quiet life. The evening was spent with me being sick because in an effort to stop me crying, my great-grandfather had been feeding me chocolates, despite my mother telling him not to as I had a tendancy to either vomit or become hyperactive if I ate too many 'e'-additives. Historically, I am still blamed for "not sharing" my gift with my (Golden Child) middle brother.
When I was 6, my parents decided we were spending the day at home, just the three of us (my brothers chose to live 300 odd miles away with my mother's parents). Usually we spent the day with my father's mother, her life-partner, his brothers and by this time, their children (who would have been newborns at this point). I went to bed absolutely fine on Christmas Eve, but woke up the next morning miserable and wretched. Like a previous poster, I couldn't even work up the energy to open my presents from Santa, and spent the morning tucked up under my blankets on the sofa. My mother (a nurse) insisted that I be taken to our local hospital's A&E department, so I was carted off into our old family car, and my father drove us through the deserted streets to the hospital with me on my mother's lap in the front seat. I was violently ill on her during the drive. The doctors couldn't find anything wrong with me, and I was sent home again, despite my parents protestations that I wasn't "right". Once back home, I again cocooned myself onto the sofa and watched my parents unwrap my gifts in an effort to get me interested. Not even the Barbie camper van was enough to get me off the sofa. My mother called the emergency GP and, perhaps luckily, it happened to be our family doctor who'd known me for most of my life. I bit him when he tried to palpitate my belly. He said to just keep an eye on me, if I got worse, blah, blah. In hindsight, and he admitted this himself, I was having a severe anxiety attack/depressive episode. It is, however, referred to in the family as "The Christmas That [13] Bit The Doctor".
When I was 19, I'd newly broken up with my abusive ex-boyfriend (not knowing that I was pregnant at the time!), and went out clubbing with friends from work after our Christmas Eve shift. My mother's parents were staying with us for a few days, and I was doing my utmost to avoid them. I spent the night asleep in my (male) manager's car after having had my drink spiked, and him rescuing me from some randomers. He lived in another town and didn't know where I lived - and I was in no fit state to tell him - so he drove me home with him and fetched a duvet from his bed, then spent the night watching over me in case I was sick, having passed out. He then drove me home the next morning once I'd surfaced, having explained why I was freezing cold and in a car on his drive (he lived with his parents), and I walked into my parents house at around 7am. My early rising grandparents were not amused or impressed by the state of me. I spent the rest of the day trying to defrost, pretty much. Oh, and my grandfather somehow knew that I was pregnant... and didn't say anything to me about this knowledge! He just sat and gave me narrowed glares every now and then. My parents? I don't think they actually knew I'd not made it home the night before. This is referred to as "Why Didn't My Grandfather At Least Tell Me That He Thought I Might Be Pregnant?!", and "The Christmas I Had A Very Lucky Escape!" (my manager and I are still friends now, and I'm still very grateful that he was in the right place, at the right time to rescue me that night).
When I was 31, I woke up on Christmas morning with the 'flu. Not ideal when you have excited children and you're a single parent! Especially not when it's the first time you've been "allowed" to host the big day in your own home. I spent the morning building my son's toys, listening to my daughter pontificate about her gifts, peeling vegetables, and crying. My father took over with the cooking and made me retreat to the sofa, whilst my mother took over with the children. This is referred to as "The Last Time [13] Is Ever Allowed To Celebrate Or Host In Her Own Home" by my parents and daughter. Luckily, my son was too young to realise what was going on.
Last year, I ruined Christmas by being unable to stop laughing at the look on my daughter's face when she bit into a chilli flavoured chocolate brussel sprout during a game of Sprout Roulette that my mother had bought because she thought it might be fun to play. My daughter then threw a wobbly (she was 23) and refused to sit at the table with everyone else, because I was there. I am, however, blamed because I couldn't stop laughing. I was "cruel" and "a nasty cunt" for this face, so...
This year, I forgot the crackers - which apparently ruined the entire day for everyone. Not entirely sure why, but I got blamed for the lack of exploding bits of paper full of plastic tat.
