When I was a little girl, I was walking with my father in Puerto Rico. I saw a lady wearing a simple, long, brown robe. Hanging from her waist were large knotted Rosaries. My Papi explained to me that she was making "Una Promesa", a promise. Either in petition or thanksgiving for a favor from God, she would wear her "habit" for a year and pray the Rosary every day.
Our final conversation was sweetly entwined with praying the Rosary.
