Mr. Green is a music teacher in a school. He lives in an apartment building in Star Community. He is kind and all his neighbors like him.
Mark lives next to Mr. Green. He has a guitar. He always plays the guitar at night. But he can't play it well. It is very noisy. All his neighbors can't sleep well and they feel angry about that.
One Sunday, Mark comes to Mr. Green's house and wants to learn to play the guitar from Mr. Green. Mr. Green says, "Young man, I would like to teach you to play the guitar, but not today. I must talk with you first. I feel happy that you also like music, but it's not good to play the guitar at night."
From that day, Mark doesn't play the guitar at night and his neighbors begin to like him.
