Sonatina giggled a bit before holding Cloff's arm and the viola, and began to demonstrate how it was played. His arm was big compared to hers and was rougher. Sonatina poked Cloff's nails and shook her head before taking her slate-board and began to write something with her left hand hurriedly. However, Sonatina seemed much more intrigued by something else as she rubbed out her original words quickly, replacing the words with: Why didn't you sing? You sing nicely. Sonatina gave a confused look at Cloff. He replied with a simple, but warm melody consisting of a pattern between four different notes.
Sonatina listened to it before realising something, I've got to go actually...
"Sorry," she said before hurrying past Cloff, making sure that he didn't see a single tear that had poured down her cheek.
