I want to use the English idiom 'don't judge the book by its cover' to talk about books. We sometimes buy/read a book because we are attracted to the cover and then we feel disappointed arfter we read the book.
Do you judge books by their cover?
I don't judge until I read but I may buy a book because of its cover.
Honestly,yes.I don't know why!
If it's the first time, I see (or came to know about) that book, then its title and the cover page sell it to me.
