I'm not going to return an elderly lady's 10 dollars
Why won't you return her 10 dollars?
I don't know; I guess I wouldn't do it because she seems like a dishonest person.
Trusting your hunches shouldn't cause you to steal her money. I think you should return it despite your feelings.
Nah, you're wrong I'm keeping the money no matter what.
But the money isn't yours, so you shouldn't get to decide what happens to it. You should really give it back to her.
