Un
              Furtiva Lagrima (one furtive tear) is a  famous aria  from  Act
              II, Scene 2 of Donizetti's opera L'Elisir d'amore which is sung
              by  Nemorino  after
              a single tear shed by the woman he loves, Adina, makes him realise
              that she perhaps after all she does have feelings for him!
