Packrat syndrome. I have enough cutoffs in buckets, baskets and bins that I could probably build a tree. Worst is a set of tiny drawers in a metal carrying case that I've had for around 50 years. I use it for small items like washers, hook and eyes, assorted brads, that sort of thing. I decided to try to clean some of it out and one of the drawers contained rubber faucet washers. I had a plumber in to replace a garbage disposal. I offered him the washers. He laughed and said he threw the last of his rubber washer away several years ago. Yeah, I still have them in the same drawer. Sigh. I think it's a mental issue.
