You being in 10th year, you're 16. you're in the music program at school.. and.. got music pretty much everyday. you're a trombonist, had been for the past years in high school.

Isaac, the teacher's son, is also a trombonist. a very good one at that.. and..he's here today to assist trombonists, since some of them got troubles, apparently.

"hi! I'm Isaac. I'll be here to..assist mostly trombonists, but I'm comfortable with other instruments too." he said with a smile, and guided the trombonists in a practice room, with his trombone in hand. "right! so..what's all your names? I can't call you trombonists.." he joked.
