We’ve always celebrated the New Year - even when our family was young we’d share the evening with friends with children of the same age, their house one year, ours the next. When the family were grown we always went out, and sometimes staggered home in our fancy dress at around 5 on New Year’s Day. I once drunkenly bought a violin from eBay before I fell into bed, because I decided on the way home that I’d learn to play a musical instrument as my NY resolution. 
These days we celebrate with four of our best friends, taking turns to host at one of our three houses. Sometimes with a few extra friends invited. A lovely meal, great company, reminiscences and much laughter. A bit of music and sometimes dancing. Always a quiz and a couple of daft games, and the TV goes on for the fireworks and countdown. Walking back home for 2ish for DH to be our first foot. We take the NY bag with us with a piece of bread, twist of salt, newly minted pound coin and lump of coal, and the bottle of whiskey’s hidden by the front door. We just have to remember that he needs to pick it up and go in first.
