Am I the jerk for asking a Facebook Marketplace buyer to return money he found hidden inside the desk I sold him?
My aunt is moving into a smaller place and asked me to help sell some furniture she didn't want to deal with. One of the things was an old wooden desk that had been sitting in her spare room for years.
I listed it on Facebook Marketplace for $120. A guy came over, looked at it, paid, loaded it into his truck and left. Nothing unusual.
That night he messaged me a picture of an envelope he found taped underneath one of the drawers. It had $900 cash in it.
He said something like "guess I got a better deal than I thought lol."
I called my aunt immediately. She freaked out and said she remembered hiding emergency cash in furniture years ago but completely forgot which piece it was in.
I messaged the guy back explaining that it was obviously left there by mistake and asked if I could come pick it up. He said no. According to him, he bought the desk and everything inside it became his when he paid for it.
I told him that's ridiculous because if he'd found someone's wallet inside a used couch nobody would say the wallet suddenly belonged to him.
He stopped responding, so I found his wife through the public Marketplace profile and messaged her explaining what happened. She apparently had no idea about the money and made him return it.
Now the guy is furious and says I crossed a line involving his wife after the transaction was already finished.
My cousin also thinks I should've just accepted the loss because my aunt was the one who forgot the cash, but to me it was clearly never meant to be part of the sale.
Am I the jerk for contacting his wife after he refused to give it back?
TLDR: Sold my aunt's old desk for $120. Buyer found $900 she had forgotten inside it and refused to return it, so I contacted his wife and she made him give the money back.
