My 16 yearold daughter is usually very agreeable, obedient, loving...today she had a fit about riding her bike to the video store to return a movie. We buy her things, take her places, allow her to do things, love her, feed her, shelter her nad she says no because she has to ride a bike??? wth! She doesnt have a license yet and her dad is sick. I am doing a million things in the house. What is the deal?
