My goodness! My silk dress is shrunk. How did you wash it?
It was washed by washing machine.
It should be handwashed with cold water. It's a common sense. Don't you know it?
I'm so sorry. I have no idea of it. I washed silk dress the first time. I'll buy a new one for you or I'll give you money.
That's all right. Please ask me if you don't know how to do something next time. You can keep the silk dress if you don't mind. I think it fits you.
It's very nice of you. I'll try my best to do my job well.
