First time using Reddit so I'm not sure if I'm doing it right. Also, english isn't my first language so sorry in advance for any mistakes. I (17F) am mad/upset at my dad (51) over something pretty stupid but it keeps bothering me. For some context, my dad bought a new TV around a year ago and took the old one to use it as his screen for his computer. Since he didn't use the old one I took it so that I could use it to watch movies and stuff (which he was aware of and entirely fine with it) and plugging it to his laptop when he doesn't use it (which is often). But two weeks ago, he bought a new tower for his computer and had to take back the screen I used to transfer stuff from one tower to another while still using the TV he used as a screen. I was gone for a week (at my mom's house, they share 50/50 custody) and came back this afternoon and was planning on taking back the small screen to watch a movie, since he finished most of the transfer and only need one screen. But, he said that he was planning on keeping it since it has a better quality than the TV. What's bothering me is that he said he needed the small screen only for the transfer and then I could take the screen back and his old tower since he wouldn't use it. He said I could instead use the TV as a screen since it would be better to watch movies (which I mainly do). But I HATE that TV. I really dont wanna sound like a spoiled brat but what I'm saying is true: the quality is shit, the top of the screen is really dark, I don't think it would even fit on my desk, and (for me the main issue) it's "dirty". I'm using quotes because it's true that it's quite dusty and stuff, but to me everyone else is dirty. So, in my mind, since it spent around a year in my dad's room it's more than dirty, and taking it in my room would also make the air in my room dirty, and since the air touches everything it would make my clothes dirty, my stuff dirty and bla bla bla. The "dirtyness" wouldn't go away after a wash with a wipe or something, it'd need to spend a few months outside and a huge deep clean to not get my room "dirty", at lean in my head. It's like that with everything and I can easily have a breakdown if I touch something I consider dirty and can't clean myself. I was also planning on using the small screen for work since I have an exam at the end of the year and need a computer/ laptop to work on it. Also, my dad knows I consider other's stuff dirty, but says I could just clean it. I was comfortable with the small screen because I had cleaned it multiple times and to me it was clean enough to stay in my room. My dad could take it on the weeks when I'm at my mom's house, which i wouldn't mind at all, but the problem would be my little brother (14 I think) who spends his DAYS playing games on my dad's comptuer and prefers the small screen. So AITAH for being mad/upset at my dad and what could I do to fix this ? Any help/advice could be useful.
