Oh, my! Hoarding is such a bad word. It's a loaded word. However, I will admit to having accumulated a good bit of stuff. Most of it is a delight to have around and is forever interesting, although delightful may not convey the exact meaning. I've had and still use a couple of things I've had since I was boy scout. Other stuff I haven't had for a month yet. Some stuff become obsolescent, though never completely obsolete, merely not the first choice most of the time. Some items have become well used and show it, other items are much too good to actually use. You probably have something like that. I do have excess of some things. I have at least a half-dozen or more plastic canteens/water bottles and one reason is because a certain on-line surplus vendor likes to sell things in lots of three or more. But they're so cheap! Now, I also have a lot of boots, some of which get used a fair amount, others, rather less, but they're all usable and except perhaps for the hobnail ammo boots. I've already mentioned that I have a drawer full of knives, though I don't think I have over a dozen of all types, but only a few see the light of day regularly. In fact, my last purchase was a Mora Companion sheath knive only last week.
I long ago disposed of such firearms I owned and some of them are missed. I just don't know what I'll do when the North Koreans invade.
I'll also admit to a degree of "real" hoarding by hanging onto empty containers and the like just because they're perfect--for something--and sure enough, they ultimately get used for just the right thing.
Most of them, anyway.
