My brother gets annoyed by me having like 2-3 audio sources at a time on my computer when I try to have a conversation with him or have him take a look at one of the things producing audio and makes me mute the rest.

It slightly annoys me when he uses headphones because I want the extra background noise. But I realize that's an absurd thing be annoyed about and keep it to myself normally.

Yesterday, my cousin, whose computer is right next to my room was playing music loudly and when he found out I was taking a nap asked if he needed to turn it and down and I said something that sounded like it could be passive aggressive and then had to say something like "I'm not being passive aggressive. I actually like that noise while trying to sleep. Like people like fans for white noise".
