"You know you are always welcome here, Kat." Nikki said, resisting the urge to ruffle her sister's hair again.  She saw her sister's eyes land on the piano and she smiled as she read the girl's thoughts.  She was so happy and proud of Kat for not letting the tragedy of their parent's death stop her from playing the piano.  Nikki wished she could stay around and listen, it always soothed her to hear Kat play the piano.  Unfortunately, she had to be to work at ten.  "You have any other plans today?"
