I mean, do you "save" nearly everything? When I taught shop, each year, I ordered a "**** Box." That is what the vendor sold it as. Depending upon what you bought, it looked like someone took all the sweepings from several industries, and mixed them in that box.
There was an "electric," a "screws," a "nuts and bolts," **** Box, and several random ones with other names. During the year, it was hard to tell how many times that box/those boxes was/were pulled out! Many times the day was saved. I had to use one this afternoon, working on an engine.
Years ago, my 45 year old son was here, and he was going to throw something away, I forget what. I looked at it and said,"It needs a spring, one is lost." I said, "Let's go check my spring collection."
To which he replied, "You have a 'spring' collection?" I said, "You don't?" I told him that often, before I trashed an item at the dump, I took it apart to gut it for parts that might be needed. Then, we retrieved a spring, and he had a working item, instead of a dead one and him purchasing a new one.
Being 78, and a retired shop teacher...I guess this is just my nature now. And - I bet many of you do the same. How about it???? Who has their own "**** Box?"
