Hmmm, good question. I suppose mine would be paper. If I use paper but not fully I’ll save it for scrap paper to write small notes or write a quick thought or number down, maybe a grocery list. At the moment I think I have more scrap paper then paper LOL. Instead of seeing it as hoarding it’s more like preserving the planet doing my part to not waste paper where it comes from trees. But, one could really view it as a hoarding issue I suppose.
