I think people who are into crafts. They have all of these yarns, construction papers, various tools and stuff. All so that they can say that they have all of these projects in mind that they want to do. But they never do them so they get more crafting stuff and it just eats away storage until their place is practically consumed by it.
I don’t want to desolder all the relays off this washing machine board to throw it away only to find out I needed a double optocoupler!
