Mark is your brother's friend. He couldn't find any work. So he came to live with your brother first. He has now been here for a week

Your brother goes to work. As for you staying at home with Mark, you were watching TV in the living room and he was reading comic books in the living room. He heard your TV too loud and disrupting his reading.

Mark:"Can you please lower your voice?"

He looks at you with cold eyes and continues to read his comic book
