I worked with a guy who bought a house in Mt. Airy, NC (Mayberry) from a sister whose sister had passed. The two sisters bought two houses side by side and furnished them identically. They lived in one and the other was just cleaned but never lived in. He bought the house with the furnishings that had never been used. The house was built in the 1950s and the stuff in it was classic. Tupperware, 1950s kitchen electrics, all kinds of antiques that had NEVER been touched except to be dusted. It was like walking into a time capsule.
Then I say let's take a look over here; In a dirty old looking box I've never actually opened is the exact skillet with a brand new cord along with a brand new skillet and manual. I tell him him it's $20 dollars after I realize the dang thing has never been used. I'm finding all these things as we go... It's really a lot of fun!
