Sounds like you have a very enjoyable Christmas when you all get together. I’ve been the last one left in my family since 2013. I’ve been divorced since 1979, so the holidays here are spent with my two sons. My niece from my brother’s marriage called me a short while ago. My sister-in-law lives with her and her family which consists of her wonderful husband, two sons, ages 21 and 19, and their twin girls, age 16.
Not sure your age. But here, at least, there is the Christmas dinner at the senior center. And I play music so having a band session with other “seniors” is always a fun get together for the holidays and the people with no more family always love it. Merry Christmas and God Bless.
