I came back from shopping with my wife and discovered my phone was missing.

I called it, and someone answered—an elderly woman with a very kind voice.
She said she found the phone and had been waiting for a call so she could return it. I thanked her profusely and gave her my address to pick it up.
When I arrived, she was waiting downstairs. I went over and said, "Auntie, you're such a good person, thank you so much!"
She waved her hand: "Don't mention it. Be more careful next time. If someone else had found it, they definitely wouldn't return it."
Once I had the phone in my hand, I was about to leave when she suddenly called me back: "Young man, you're just going to leave like that?"
I was stunned. She said, "You should have a conscience."
I said, "You're right, thank you for returning my phone. Let me transfer you 200 yuan as a token of my appreciation."
She frowned: "Only 200? This phone should be worth at least 1,000, right?"
I was taken aback. I said it was an old phone and wouldn't sell for that much, so I offered to increase it to 300.
She was still unhappy: "At least 350."
In the end, I transferred 350 yuan to her.
On the way back, I kept wondering: Is this auntie a good person or a bad person?
