I can make a guitar sing
Making people think you're the most trustworthy person, then stealing their last $20.
I told my friend I'd help him move. He believed me. Now he's out $20 and I'm laughing at him.
She said I could borrow her phone. I believed her. Now I've got a broken screen and a $10 bill.
He told me I could win the lottery. I believed him. Now I'm out $20 and I still have no money.
