[Brooke does notice the mermaid princess relatively quickly into his playing, as she is easily ten times the size of an average person. Still, he notices that she seems to be enjoying his playing at least, so he doesn't feel the need to interrupt his reverie to entertain her through some other method. When his song is complete he takes a bow.]

Thank you very much Mermaid Princess! The reason it sounds so sad is because it is a little bit sad, as it is in remembrance of some of my fallen friends. Sometimes I like to honor their memories with this piece, and it takes me back to a time when they were still with me.
