Fortunately my wife never goes down into the basement nor up to the room over the detached garage or even into the greenhouse, and she otherwise ignores my mess in the garage. She knows that there is a lot of food and other stuff down in the basement, just not how much.
I too wish I hadn’t tossed or given away a lot of stuff that I did, especially some of my father-in-law’s old tools when they moved into senior housing so many years ago. He had some other good stuff too that I gave away. I’m much better at tucking away “maybe this will come in handy someday” stuff now.
