I'm going to sell your sunglasses
Why would you sell my sunglasses?
The reason is minimal useful life
They're my sunglasses so you have no right to sell them. If you sold my sunglasses, I may take you to small claims court just to spite you for your insolence.
I'll sell them if I want to!
I hope you realize that you will be committing a criminal act if you deal in stolen goods. You simply can't sell things that are not yours.
