As the song ended and he stopped playing the emotions he projected took a few minutes to fade in intensity. "Still tweaking the second verse I think." He said, making a note in the book next to him. Cassidy looked up to her with a small smile. "Will sound much better with a piano." He said again, as if to blame that on if the song didn't sound right. Cassidy wasn't insecure a lot, but the one time he had any insecurities- it was about songs he'd written. He could play others songs all day and night and know he was doing a good job- or laugh at himself if he fucked something up. But when it was his own creation it was a bit more personal.
