My tongue was firmly planted in my cheek with the judgemental statement about people’s motives. It’s their money to do what they want with, so unless they’re doing something illegal, unethical, or immoral it’s really none of my business.
However, just from a purely speculative position, the things that revolve around my home are, generally speaking, the things that I would want for my family to enjoy an experience, and not just for me and my wife…..not that there would be anything wrong with wanting those additions just for personal reasons or to please the wife. It’s just not how I am built, and I’m not saying I’m better than anybody else for thinking that way. Simply put, I truly just don’t understand why someone would want more stuff to take care of as they get older. I’ve known quite a few successful people, business owners, entrepreneurs, etc, who began downsizing as they got into their older years. Granted, I’m speaking of people when they get into their 70s and 80s in that regard, not somebody who might be able to retire in their late 50s and begin to actually still enjoy traveling, and other amusement. I say, good on you if you’re able to do those things, as I hope to do them as well. It’s just in that one isolated example of home expansion that baffles my thinking, but again, I’m not judging others who do, just don’t understand it.
All of that is pontification that is far afield from the OP though, and I would definitely not characterize somebody who wants to do a home expansion in the context of how you present it as “going through a midlife crisis”.
