M: I'd like to return this sweater for a refund. I bought it a week ago.

W: Well, what seems to be the problem？

M: Isn't it obvious by just looking at it？ The first time I washed and dried it, the thing shrank at least five sizes.

W: I see what you mean, but did you follow the washing instructions？ I think it says here ... right here on the label to hand wash it and then to dry it on low heat.

M: How was I supposed to know that？ The label is written in Chinese! And something else i The stitching is coming undone and the color faded from a nice dark blue to a seaweed green.
