It is presumptous, yes. But among the few (soon-to-be-) retired peers I know well enough to discuss the topic, many have a concern about retreating to a chair in front of a TV for the rest of their inactive lives. We've seen others do that far too many times. And that is a particular danger here in the winter.
DW and I are in transition. She retires in just less than three months. Right now I am the househusband; with the exception of clothes washing and buying gifts for others, if it happens in or around the house, it's because I've done it. It's not a full-time job but it takes a fair amount of time. I'm okay with that; I see it as my contribution to our partnership and the household. That will change, though, once DW no longer has to go to work each day. I'm okay with that, too.
In the space of the six weeks around DW's retirement, a long-time volunteer gig of mine is ending (moving much further away than I want to drive and changing in essential form as well). My term as president of a new non-profit is ending (I'll still be involved but it won't soak up nearly as much of my time as it does now). I'm going to have oodles of free time real soon.
And, right now, I don't know what to do with that time. I will pick up a new volunteer gig. There are a few long-standing projects I'll now have time to dive into, but they won't take that long. DW has talked about starting a consulting business in her field because she knows she wants some structure to her retirement days. She does not envision it as a 40-hour-a-week engagement. I've told DW I'll be her back-office support for the business, at least at the beginning.
But I'm so used to living "on-call" (grandkids sick at day care? I can get there before anyone else can. Tradesperson coming to fix something or give us a bid? I'm here. Sign for a package. Yo...) that it will take time to get used to not being the one who does that. I'm good with not having so many deadlines or appointments and having the freedom to declare a "snow day". But, right now, anyway, I do want to put a bigger ding in the universe than I'm doing now. Time and opportunity will tell.
