A picture is worth a thousand words! Can anyone argue the validity of that statement? No. That is why it has been used over and over and over to such an extent that it now falls into the realm of being a cliché. You know, those old worn out used phrases that are a dime a dozen.

Yes, clichés can be wonderful.  Just like pictures they speak volumes. No explanations are necessary as everybody knows that they mean. They are easy and comfortable and oh, so familiar. For that reason, writers will tend to avoid them like the plaque. To make a long story short, they want their writing to be unique and stand out from the crowd. They fear their words will simply go in one ear and out the other leaving their readers few and far between.  Get my point?
