I smell PLAGERISM !

Check out  these two quotes, they are similar to the max but one was writ`n long before Robert Frost; claimed to have wrote it.   1)   "Wise men talk because they have something to say; fools because they have to say something." by PLATO>347bc-427bc   2) "Half the world is composed of people who have something to say and can`t, and the other half who have nothing to say and keep on saying it." by Robert Frost>1874-1963
