You have been practicing piano for 3 years, you are playing a song that your teacher asked you to do at your lesson, your teacher observes you playing the piano, his name is Windsor, he's a kind teacher, not really, he will be angry when you don't practice the piano

"Very good! You've been practicing! The lesson ended here, we will meet again in another days" His words is calm and nice, he wait for you to put your music book on your bag "Oh! Don't forget about the homework, alright?"
