Rock Solid

I used to have a solid friend, Whose name was Limestone Jim. Although he never spoke a word, I often had long talks with him. Now, I could always find him In his place, up on the hill, And if only he had listened, I am sure that he would be there, still. I told him to be vigilant Of dangers, around the clock. He never showed an ounce of fear; Old Limestone was a mighty rock. I tried to warn him many times, But he couldn't see things my way. So they crushed him into gravel, And spread him on the highway.
