My ex-wife and I went round and round on that for years. Garage was so full of her junk, she didn't even know what she had anymore. I couldn't even get to my workbench. Every time I brought up the subject, it was always, "That's all your books out there!" Uh-huh. When we split up and moved out, yeah I had a few boxes of books; but that comprised about 1% of what was out there. The rest of my stuff brought the total to about 15%. It finally sunk in when she had to move out her own crap.
That's some good schadenfreude there!
My wife has been saying we need another shed. I say what for, do you really want your seasonal decorations (at least 5 seasons of decorative stuff that has to go up and come down and packed back on the garage shelves) and fabric, etc. to sit out in a non-climate controlled shed? I keep the garage from freeezing or getting above about 77.
I'm like, "honey, no matter how much more space we get, we're just going to fill it". We are getting to the age where downsizing would be smarter. But I cant say too much, I am a notorious pack-rat myself. I have a gazillion pieces of material, metal, wood, etc. I "just know" can be used on something! And its true, sometimes I will actually use something I kept 15 years ago with that thought!
I have her at bay dreaming for now. I had my parents build a house on 2 acres I subdivided off my property for them. They built a long cabin. Kind of a high maintenance house for the long term, but the plan is of course when they pass (they are 82) I get their estate (only child) if I actually out-survive them...no guarantees in life! Of course I will be there if they become infirmed and need help. That was the original impetus for them building next door.
I dont really want someone I dont know living there so close (maybe 75-100 yards through the woods), and actually dont want even family like one of our kids living there. So I told the wife if we can afford to keep the cabin, she can have it for her sewing studio as long as we keep one of the bedrooms for guests (which I also prefer to avoid!). It's like visions of sugar plumbs dancing in her head! She insisted that she would still come home for dinner, etc.. Of course, I do 99% of the cooking!
