I'll open some presents with my mum on Christmas eve evening before I go to work. Depending how busy it is I should be able to close the office about 2/3am. Get home, greet my ever loving dog and whisper her a Merry Christmas. Go online for a little bit no doubt before sleeping. Get up around 9/10am. Wish mum a Merry Christmas. Waste away a couple of hours being bored until we head to my aunts (mums sister) for Christmas day with my nan, where in all likelihood it will be her last (she has cancer). Have a great meal there with loads of laughs. Walk home myself in the late afternoon to pick my dog up and walk her round to my aunts where my aunt will fuss over her ridiculously. Have some pudding, some gifts, then go home when my nan is tired.
If my Christmas Day differed from any of this already planned event then I will be very upset.
