person B: I am so sorry to hear that. What did they do to make you feel uncomfortable going there?
person A: They were a friend and customer of mine in a small business and cheated me out of a large sum of money.
person B: That's the worst! You think you can trust people_comma_ and then they stab you in the back. I don't blame you for not wanting to see them again.
