my older bro is such a baby

ok so like my big bro and i have this thing where he always says i’m the one with issues even though hes constantly overreacting to literally everything. last week i was just chilling in my room listening to music when out of nowhere he starts pounding on my door going off about how i’m playing it too loud, like there’s no way that could be true but whatever i turn it down anyway and next thing you know hes still yelling through the door asking if im serious about lowering it because its making his “head explode.” seriously. hes like 23 and acts like a 5 year old. we got into this huge argument over some dumb noise complaint, when anyone with ears knows my room is like two floors away from him in this house. i dont understand how he could be so worked up about something that simple. honestly the only reason im even saying anything is because every time mom asks if everything’s fine between us and we’re getting along i feel weird not mentioning it. i know hes gonna blame me but really, like how do you argue with someone who gets mad at a whisper? it just makes no sense to me.
