"Are you going to Scarborough fair? Parsley, sage, rosemary and thyme. Remember me to one who lives there, for he was once a true love of mine." She hummed a few bars then started "’twas the last rose of summer, left blooming alone. All her lovely companions are faded and gone." A few more hummed bars and she started again "Oh the oak and the ash and the bonny ivy tree. They flourish at home in my own country." Draco realized he was standing there just listening to her instead of paying attention to his work.
