I completely understand your frustration with this situation. Perhaps you can have a mini-reunion/potluck dinner at your home around the holidays. The most important thing is this, once your family is gone, that's it. My dad was one of 18 children and now there are 2 left; my dad and his baby sister. I remember growing up as a child with tons of uncles and aunts. Never thought I would see the day, literally, when it would get down to this number. When you have to keep burying relatives over and over again, you realize that petty stuff about where to have a reunion, how often, and what activities to plan are silly in the grand scheme of things. Reunion or not, please keep your contact with your people.
Peace and Blessings
