It was 10 pm, and our parents were asleep. Me and my 2 other brothers (older and younger) were at the kitchen table chatting around. I went upstairs to bring something to show my little brother. My big brother asked me something while I was on my way up, and didn't want to speak back otherwise I'd yell, so I said "shh, just a moment". He said "What?" Didn't respond and just went on to bring my item. While I went downwards he replayed his question and I silently told him "just a moment". I came back, he asked me if I want to eat the sushi or he can put it in the fridge. I told him to leave it to me (Jesus, I hate those micro-management questions).
I was showing my brother what I wanted to show him, and he was on a call with his friend. From there while he was preparing to leave to his room he told him "Hold on, it's just that my brothers are waking up my parents."
Got angry and replied (not loudly) "No we're not, you're also waking them up", to which he did not reply.

Despite replying to him, I still feel the sting and it hurts.
It just hurts, and I have NO idea how to get rid of the pain!

I hate it when he's excluding himself from responsibility and being the "authoritarian big brother" / "vice father".
If I'm staying at home during university, I don't know how I'll be able to put out with that.

So how on Earth do I let that anger go?
