The husband apologizes to his wife for hurting her sister's relationship with her parents. The wife expresses concern about her sister's hurtful comments, but the husband agrees to talk about other things to cool off before talking to her again.
human
What's wrong, dear? You seem upset.
gpt
It's my sister. She said something really hurtful on the phone.
human
Oh no, what did she say?
gpt
She said I was always the difficult one in the family and that's why I don't have a good relationship with our parents.
human
That's not true at all. You're not difficult, and you have a great relationship with your parents.
gpt
I know, but it still hurts to hear her say that. I can't believe she would even think that about me.
human
Maybe she's just going through something and taking it out on you. You know she loves you and wouldn't intentionally try to hurt you.
gpt
I hope you're right. I just need some time to cool off before I talk to her again.
human
Of course, I understand. Do you want to talk about anything else to take your mind off of it?
gpt
Actually, I was thinking about the time you put together that rocket and went to Mars. That must have been exciting.
human
It was definitely a once in a lifetime experience. But nothing compares to the feeling of being with you here on earth. 
gpt
Aww, you always know how to make me feel better.
