I can't believe you would do that! I pulled your shirt hard because I wanted you to understand the gravity of your mistake.
gpt
Ow, that hurt! What are you talking about?
human
You know exactly what I'm talking about. You broke my favorite mug and didn't even apologize for it.
gpt
I'm sorry about the mug, but there's no need to get physical. Have you considered that maybe you're overreacting?
human
Overreacting? That mug was the only thing I had from my grandfather, and now it's gone forever. You don't understand how important that was to me.
gpt
I didn't realize it had that much sentimental value to you. I'm truly sorry for breaking it. Is there anything I can do to make it up to you?
human
I don't know. Maybe just be more careful with my things in the future. And apologize when you do make a mistake.
gpt
I promise to be more mindful in the future. And again, I'm sorry for breaking the mug. Can we move past this now?
human
Yeah, I guess we can. But please try to understand how much some things mean to me before you're too quick to dismiss them. 
gpt
I will definitely keep that in mind. Say, do you remember when you asked me to marry you? I still get butterflies thinking about it.
