One child is 7 and the other is 12 but about to be 13. Let's say the two children like to watch TV with very high volume the whole night until early the morning because they are in summer vacation. The noise coming from the TV is so loud that it does not let me sleep. The children keep repeating this behavior day after day. One day I tell the children to please lower the volume and they do it, but five minutes after I come back to bed, they raise the volume again. I ask the politely to lower the volume again and they do it, but once again, when I am in bed and trying to sleep, they raise the volume of the TV. At that moment, I am feeling frustrated and I no longer ask politely to lower the volume from the TV but I demand it. A second time I demanded to do it, and they begin to cry for mom.The children are not his children. He is a tenant and their mother is renting him a room within the house.
