This is a book of cliches. whatever you aretrying to say, there are no two ways about it - someone's already been there before you. From centuries-old sayings, like beggars can't be choosers and a friend in need, to today's tried and tested phrases, such as at the end of the day, not fit for purpose and it's not rocket science, the English Language seems so full of cliches that sometimes it has to be seen to be believed.
