Angels stay on top of things. Angels walk softly and carry a big presence. Angels travel lightly. Angels promote closeness and foster tenderness. Angels don't make too much noise when they flap their wings.
Angels know how to pull the right strings.
Angels don't sing the blues. An angel's art is his heart. Angels are always memorable because they never forget what really matters. Angels can't read music, they wing it. Angels can fly even though they are well grounded.
