There are several. Sometimes we have to change the date so that we can get together.
I would say my favorite is related to Christmas. Some activities I have let slide, and would like to bring back. Such as the lighting of Advent Candles at home. I have been lazy about it since my nest became empty. We always have a door decoration. I am usually with the family of my only granddaughter either Christmas or Christmas Eve, if not both. That is my favorite time. We are also trying to pull in my step-daughter and her family that includes two little ones.
Something I want to keep going is making and Advent gift box for my granddaughter. I need to get started on that, so it will be ready. I spent about $15 on the gifts last year. I bought a package of colorful markers, and separated them into about 8 gifts. So, doing things like that kept the cost down.
