I (16f) have a mother (59f) that is a very light sleeper. She like to sleep with the TV on at night with YouTube videos on in the background.Iend up turning her TV off almost every night and have repeatedly told her not to leave it on because we are on a certain data plan and when she leaves it on at night it eats all the data up.( I should also mention I'm online for school so I need the data threw the month) Well, sometimes I wake her up at night because she sleeps with our yappy Little Chihuahua, and then she acts like she was watching it when she clearly was not and doesn't let me turn it off. I've really gotten upset over this because it seems like she only does it to spite me. I've also tried to come up with solutions, like her putting a sleep timer on her TV so when she inevitably falls asleep the TV will shut itself off. She did it once and refused to do it again. So recently I've started using the Roku mobile app to shut off the TV from my room when I think she is asleep ( this is where I think I'm the asshole) well one day, she just so happed to be up when I thought she wasn't and came over to my room to see what happened and that's when I told her I've been shutting it off every night. She got pissed and basically told me I had no right to even if she was sleeping and that since she pays for the Internet she can use it as she pleases. I then got into a screaming match with her and said "well if your ignorant ass didn't use all the data in a week I would t have to, Ive given solutions and you didn't use them so it's your own fault I've had to resort to this". I didn't want to yell but I don't see the issue with me turning off her TV when she's unconscious, especially since I need the data for school. She has since changed the password to the Internet and won't tell me what it is, so I've had to go to the local library to do my school work. I don't think ITA but tell me, AITA?
