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 pretty much had to set a limit with my wife. Like you can have these 4 giant tote bins filled with yarn supplies and two baskets of projects in progress but if you want more than that you have to give some away.
I had to make a boundary because it was getting out of hand.
