I was a little upset that my friend wanted to charge me for the cups being broken.
I understand your feelings. How did the cups break?
She was the one who did it. She never mentioned the payment ever taking place.
I agree that she shouldn't be charging you for cups that she broke. I'm sure this is upsetting to you. She should really cover the cost of the cups if she's the one who broke them.
I'd say I'm more angry that she started making a big deal saying it's not fair.
It's understandable that you're angry and disappointed in your friend's attitude about the broken cups. It's important to share your feelings about this with your friend.
