What does 1 Chronicles 15:29 mean?

As the chest of the covenant came into the city of David, Saul's daughter Michal watched from a window. When she saw King David dancing and celebrating, she felt nothing but contempt for him. 1 Chronicles 15:29 - Modern Text Bible

(Michal saw David's open joy and thought it was beneath him as king. Her reaction stands in contrast to the joy and humility shown by David and the others.)
