I think the negative connotation attached to the word "hoarder" has been promulgated by our throw-away society. When you save stuff and re-use or re-purpose things, it means you aren't buying new things, which means those businesses aren't making as much profit as they think they are entitled to. Of course, there is a difference between someone that hoards things because they know they will be able to use it again someday, and someone who's simply too lazy to take out their trash!
Though grandma used to use the bigger cup side to start seedlings. . Lol woops getting carried away here ^,^; so much repurposeing!!! >,<
