Relative pronouns , provided they are not the subject , are often dropped in short restrictive clauses : '' That 's the man who I saw . '' Note that the dropping of pronouns is generally restricted to very informal speech and certain fixed expressions , and the rules for their use are complex and vary among dialects and registers . A noted instance was the " lived the dream " section of George H. W. Bush 's speech at the 1988 Republican National Convention
