It was the only tv I could use in the house
Why couldn't you watch TV anywhere else?
I live with my parents; I could only watch it on their TV, and I wouldn't let them watch their show.
If you live in a house with other people, you have to compromise with them on TV watching. You can't always expect to watch whatever you want and neither can they. You have to take turns or work together to pick shows.
It's hard to have a conversation with my parents about sharing the tv since they seem to be deaf to my wishes.
I understand that you want to watch your show, but other people in your family have tv rights also. Share with others if you want them to listen to your wishes also.
