Yes! Christmas for me is the couple of weeks before - love all the lights and general build up at that stage. But the day itself and everything afterwards is a proper chore. Hate still seeing the lights up well into January - like you say, it creates a sadness after all the festivities.Christmas lighting any time after Christmas Day should be switched off.
It's ok in the lead up to the big day, but there is something sad about the things after the event.
Never mind the twelfth night thing, be done with them now.
