I hate my brother so much right now

I'm on the verge of crying.My brother knocked on my door so loudly because my cat was meowing outside my door wanting to get in. I said later and he just kept knocking and knocking and when I opened the cat was not there .Then I said 'THE CAT'S NOT HERE ' and he started knocking on my door to annoy me.OMG SO IRRITATING.I felt like hitting him but I'm not gonna start something.Anyway after that he just kept walking past my room and knocking and when I asked him to stop he said 'I don't want, I want to annoy you' IRRITATING ASSHOLE...UGH....
