Quoted from jwilson:He even said "My loss," implying that he figured out it was worth a lot more than his asking price.
As a seller, it makes zero sense to turn down more money for something I'm selling if offered. If you're telling me you'd do so and be happy about it, I don't believe you.
I wouldn't be "happy" but I would do it, because I'm a man of my word and it would be my fault for not finding out the true value before listing. The seller is a man of his word even after finding out it was worth a lot more. That's a real man, something you don't and won't understand.
