Recently my neighbor left her refrigerator on the front lawn for a week. When I arked why,she told me she didn't want it and she hadn't had time to take it to the recycling center. It was a good fridge,so I told a local secondhand store who came and took it away. I didn't expect it,but the guy gave me $40. When I told my neighbor,she demanded I give her the money. I refused,because if she had wanted money for it,she could have sold it herself. I mean,wouldn't you have kept the money? Anyway,since then we haven't spoken at all. We were friends before and it's ruined a good relationship. What should I do?
