I'm telling the truth.
Believe it or not, that's the way it is.
I wouldn't lie to you.
I wouldn't try to trick you.
You've got to believe me.
Why would I lie about this?
You can take my word for it.
You can count on me.
You lied to me.
You told me wrong.
I'll never trust you again.
Stop lying to me.
I can tell you are lying.
You can fool me once, but you can't fool me twice.
I don't buy that.
Why didn't you tell me about this before?
A: I just found a bag on the street with one thousand dollars in it.
B: What? That's a lot of money. You have to turn it in to the police.
A: Are you nuts? You are right, it is a lot of money. I'm keeping it.
B: But it's not yours. Just think if you were the person who lost all that money, how would you feel?
A: Pretty bad, but I'm not that person.
B: Don't be so selfish. Do the right thing. Besides, if the police can't find the owner, they will give the money back to you, and even if they do, the owner will probably give you a reward.
A: Well, I guess you're right. I would feel a bit guilty keeping it. Okay, I agree. Let's go to the police station together.
