Hey there, I spent it with my sister and her boyfriend (now Fiance) as they got engaged on New Year's Eve, so it turned into a celebration! I generally don't like it either but this was a different one for sure!
My sister, had a very good reason for really disliking NYE....For NYE 1999 into 2000 we had bought bottles of champagne to help celebrate the big one. When the clock struck midnight my Dad popped one of the bottles and my brother the other bottle. We were all celebrating 2000 and I noticed my sister had crouched down. When my brother opened his bottle of champagne, the cork hit her in the eye!! We always joke that she has PTSD about NYE but now it will be replaced by a nice memory of her b/f proposing. He went all James Bond on her and dressed up in a dinner suite. They are together 8 years and it was obviously on the cards, but she was rightly surprised.
Sounds like you all had a lot of fun. Last year, on NYE, I did nothing because I had a wedding the next day. My cousin got Married on New Year's Day last year and it was lovely. Although, we had all started to worry as to weather or not we'd be have a wedding with all of the snow, but thankfully it had thawed. What a contrast this year was. It was so mild, like 13C !!
