Paul Laurence Dunbar - The Debt lyrics

This is the debt I pay Just for one riotous day, Years of regret and grief, Sorrow without relief. Pay it I will to the end -- Until the grave, my friend, Gives me a true release -- Gives me the clasp of peace. Slight was the thing I bought, Small was the debt I thought, Poor was the loan at best -- God! but the interest!
