What they are really saying is, "Don't judge a PERSON by their outside appearance." Some books have pretty covers... but it is not a good book. Thes same is true with some PEOPLE. Some books look bad on the outside, but the book is good to read. The same is true with some PEOPLE. I suspect you might not be familiar with this because maybe you are not an American?? In a related story, I once knew a nice Vietnamese lady. She told me a vietnamese "Quotation." It goes like this... "If a water-buffalo looks at the moon -- it means nothing." Maybe you might write a hub of quotations from whatever country YOU are from? If you do, be sure to explain them so we understand the meaning of them.
