A friend reminded me a while ago that family isn't everything. She's someone who has stepped up for childless uncles and aunts, and knows my story very well. One of the few IRL friends and family who reads here. We've both had to help parents and in-laws in their old age. And she's starting to downsize for a move towards her own family - not far in distance, but a big change - to fund the retirement lifestyle they want to have. (Again, another reminder for me to clean up here. Yes, the universe is trying to tell me something.)
I made a simple comment about having to ensure we are somewhere safe earlier than most people might have to think about it. People with children that is. And she reminded me that when family aren't around - either because of geographical (or emotional) distance or their non-existence - that friends are there to help. And even friends kids. She pointed out that we've been friends for almost 30 years, and her kids have always known we are part of the fabric of her life, even if we don't know those children well now (they're grown and in their 30s themselves). She's sure they'd be around for us even if she or her husband couldn't be. And I've been reminded too that others feel the same way.
Family doesn't have to be focused on only parent-child relationships. It can have a much wider definition. Blood, or not blood. Related, and not related. We need to remember that.
