"I'm just a call or text away." Kat smiled at her big sister and frowned playfully when Nikki tousled her hair again. "Friday night's good for me. I'll talk to Brad about it and we'll let you know." She was slightly curious about what Andrew wanted to talk to Nikki about, but the girl didn't dwell on it too long. "Okay, go get ready for work. I'll lock up when I leave." She smiled as she watched Nikki head upstairs and Kat walked over to the piano. Running her fingertips over the keys brought a sad smile to Kat's face. One of the only memories she had of their mother was learning to play from the woman and even though it made her sad, Kat still played so she could keep that memory alive. She sat at the piano and just let whatever melody came to mind flow through the house. Kat liked Beethoven and Mozart, but sometimes she made up her own melodies. Today was a Mozart day for Kat.
