Don Gibson - Last Letter lyrics

Why do you treat me as if I were only a friend? And what have I done That's made you so different and cold? Sometimes I wonder if you'll be contented again Will you be happy when you are withered and old? I cannot offer you diamonds or mansions so fine I cannot offer you clothes your young body crave But if you'll say that you long to forever be mine Take off the heartaches, the tears and the sorrow you'll save While I am writing this letter I think of the past And of the promises that you are breaking so free But to this world I will soon say my farewells at last I will be gone when you read this last letter from me
