Growing up my mom and I have friends who's wives have thrown (often expensive) stuff away without asking their spouse and I'm always like "uh.... what?". At least ASK first. I have a decent amount of of PC parts and various screws and whatnot that I've saved for years but they don't take up much space and they come in handy all the time. Just recently I had to fix a broken hold down thing on my PC's motherboard and I would have been fucked If I hadn't had a box of shit to look through to fashion a replacement.

I understand asking to get rid of stuff if it's in the way but if it's out in the garage with the rest of their tools or something like that and they toss it that's fucked up to me. I have shelves that are designated for this purpose and if more stuff then will fit I toss something to make room. The line for me is it being on the floor or spilling onto horizontal furniture. Which I think is perfectly reasonable.
