Home speakers

My son told me that he wanted us to go to the library tomorrow because he wants to borrow more movies. He likes to watch movies on our living room TV. He likes it because it has surround home speakers attached to it. Sometimes I tell him that I want to watch my TV show in the living room and he gets mad at me. He really likes to watch his show in our living room where he can hear all the loud sounds it is like he is in the movie theater. It makes me mad but I give up there is no sense in arguing with him about it.
