...for some people it's just nice to know that there are others around that share a somewhat rare/minority characteristic in common.
Totally.
Across this forum this is definitely expressed around variables such as autism, low income, autoimmune challenges, single parenting, adoption, alcoholic parents, location, grandparents that hoard, etc. Anywhere we find people with a distinctive and life-influencing variable in common, many of us definitely feel more welcome, safe, understood, and connected here (as elsewhere).
At least one person has talked about the potential impact of polyamory on their finances, which I found very interesting. And several members recently connected around the oddity of "wealthy parents who ask their low-income children to make expensive trips to go see said wealthy parents", or "parents who fund some of their kids' visits but not theirs". Finding these very specific matters in common seems to have brought energy and healing to people who have been feeling some angst (guilt, sadness, frustration). Finances are so interconnected with all parts of our lives: emotional, relational, psychological, etc.
Not even tongue-in-cheek, I'm a little bit tempted to name my next Journal (per new goals) with something like "Canadian, autism, no co-parent, low income", all of which definitely impact my finances, so as to welcome and build community with people who have any one or more of these variables in common with me. Not that I'd want to restrict the sub-community to that, but I acknowledge that so many aspects of who we are really do impact our finances, and also that when we find people with major yet distinct variables in common, we can feel more relief, safety, connection, hope, and encouragement in seeing their successes. To that end, I really appreciate people sharing their distinct variables and/or the more vulnerable aspects of their life journey.
