This thread is lovely! Although my eyes have been full of tears while reading it.
I remember the foil decorations (we still have some, they go up every year!).
The smell of the real Christmas tree that me and my dad made my mum put up with every year. She would have much preferred an artificial one but we were having none of it.
The sort of musty/pine-needly smell of the Christmas decorations when dad got them out of the loft and opened the boxes. That smell takes me back in an instant.
I decorated the tree every year after dad had put the lights on and even though I left home 10 years ago I still go back and decorate their tree and dad still puts the lights on first.
Having my mum's parents to stay, and my dad's mum, from Christmas Eve to New Years Day. They are all sadly no longer with us but I loved waking up knowing we had a house full of lovely people.
The bowl full of nuts in the lounge with the ancient silver nutcracker. My dad still has this every year and has endless patience showing DS1 how to do it.
Waking up in the night and knowing Father Christmas had been. I never opened my presents until the morning, I always went back to sleep full of excitement.
My mum reading The Night Before Christmas to me before bed. I do this with DS1 now.
More recently, going to midnight mass with them - last year I took the DC as well and DS1 loved sitting in between his grandparents. I hope we will be able to continue this tradition for many years yet.
To the PP who mentioned whisky in tea - my dad did this every year but I was about 17 the first time I got whisky in my tea - he brought me tea in bed and I took a huge gulp - it nearly blew my head off! He's not one for small measures...
