Before he could finish, he realized he had said the wrong thing and immediately looked at me cautiously, adding, "I don't mean for you to return it..."
Seeing him desperately trying to explain, I remembered. After setting the wedding date, his mom gave me an expensive diamond necklace and bracelet.
But I had never worn them, so I forgot about it.
I interrupted him, "I understand. I'll bring them back tomorrow. Not a single diamond will miss."
