skim milk

You know how the milk ladies at Carrefour used to drive me crazy? Well, yesterday, I was looking for the bottle that says "skim milk" in English and they were out, so I was deciding which 2% to buy, when a milk lady came up to me with a bottle of milk and told me this is the kind I want- it's skim but it doesn't have English on it so maybe I didn't know? And she knows I like to buy that kind. (Conversation in Chinese, of course.) How cool is that?
