Me and my brother always get up really early and watch TV quietly for a few hours.
At around 8 we send the dog upstairs to wake the parents up.
Then we each take it in turns to open presents one at a time.
We eat dinner at 2 every year, but we cook the turkey the night before.
The we watch christmas TV and eat lots of chocolate and mince pies :)
Boxing day we usually go to my Aunts house and loads of my family are there, so we exchange presents and generally catch up as most of the family i only see once a year. we all have to wear some form of silly chritmas clothing like a hat, singing tie or novelty earings.
we still put out mince pie/sherry/carrots!
I don't do this anymore but when i was younger i made my dad buy 9 carrots, to leave out because i thought it was unfair that rudolph got loads of carrots and the other reindeer got nothing.
