a lot of the time, i’m either busy doing something where i literally cannot respond or overstimulated.
when i’m overstimulated, i physically cannot talk or barely register what someone’s saying. i also have trouble understanding out loud speech for some reason, where i’m listening but can’t process the words.
when my sister asks or says something, i often ask her to repeat it because it’s a lot of information. she says something like “never mind, you don’t care anyway, it’s not important” when i ask to be repeated.
she doesn’t care when i told her why i need it to be repeated.
she also thinks i’m mad at her all the time, gets frustrated when i don’t talk (because im incapable), and starts talking badly about herself when i don’t laugh at her humor (which consists of loud screeching and tiktok “brainrot” words)
since then, i decided to feign laughter so she’ll not think i’m upset with her.
i do try to be there for my sister, but there’s times where i cannot or just can’t talk.
You can’t deny what she likes ; what you can do is ask her to explain: what is it about it that resonates with her? Can we sit down, turn the volume way down, and spend a few minutes checking out her fav’s in that style while she tells you why she likes that stuff?
(The subtlety here is not asking her to justify herself, but to explain to that out-of-the-loop, quite-geriatric Dear Bro)
Her answers don’t matter much - what matters is asking her to view the topic critically, and verbalise it that so that you “get” that side of her.
Also, “I love you but I fucking hate that shit” can work you know.
Good luck.
