"Don't judge a book by its cover" is a metaphorical phrase which means "don't determine the worth of something based on its appearance"...i think we'v all met someone who judge by the cover...how about you??!please feel free to comment...

it is impossible not to make some assumptions and opinions on first sight. that's why it's called a first impression. the key is to not allow the first impression to blind you to what may lay beneath.

I don't judge a book by its cover,but judge by the content of it's character.
