Sorry, but I'm not interested in becoming a hoarder

Tomorrow we're going through grandma's things to see what we want to keep. I'll mostly be there to help, as I'm not that interested in old things. Sure, maybe I can use an old pot for my kitchen, but I don't want to drag any collectibles or old furniture home. "You have to take a painting" is what my dad told me. No thank you. Of course I get that he wants to preserve those family things. But I don't want to take anything home, only to leave it in a corner somewhere to collect dust. I want things I can use. And paintings of old ships and the like is just not in my taste.
