TLDR when pressing my little brother for harassing me he fake cried. I said “I ain’t new to this I can cry too” I squatted to his eye level and did the most obnoxious cry I could do

(17M) I am not a mature person.

For months my little brother (5M) has been essentially rage baiting me. Chucking shoes at my head with amazing accuracy, seriously he should be in sports not in time out but that’s beside the point. He will run into my room if I leave it unlocked and try to break my my stuff, last week my door nob. Anything to get attention. Even going as for as to force himself to throw up and tell up to clean it. No punishment works because he finds it fun. I used to be a horrid kid in my childhood but chilled out in my pre teens. so I got good at predicting his moves when he’s pissed. He already broke a TV, His tablet several times, my sisters laptop, my moms screen, my switch’s joycon so I’m prepared now.

I tried the “gentle parenting” method but after a while my patience is running thin. While my grandmother whos our temporary guardian, claimed she couldn’t hear or see him chucking shoes at me and him yelling “I hate you” even though she was right next me me. She barely punished him.

So I chased him up the stairs, he started crying and calling for grandma, so when I backed off out of guilt he would stop crying immediately then keep it up again. So like the responsible older brother I backed him into the same corner and told him to knock it off, he started fake crying. Then I was so mad any sense of reason left my body, I said “I ain’t new to this I can cry too” I squatted to his eye level and did the most obnoxious cry I could do. I did the classic big inhale cry, then beautifully transitioned it into the classic “WAAAAAAA” before i broke character and started laughing. We deadass started harmonizing. He started crawling backwards and I was walking towards him while we were both crying at each other. He was mad and freaked out to snitch on me to our grandmother but I swear I saw him crack a smile.

When she came to confront my brother, oops I mean comfort, I whispered “HA Crocodile tears”. My grandmother said im almost 18 and im being an asshole to a baby who apparently looks up to me, whenever he does something to me she doesn’t care unless it affects her but the second I retaliate the immediately notices. I had the same thing happen with my sister (18F) growing up when we argued. my sister (in college) when finding out started laughing at what I did to him.

Thank god I’m getting a dorm.

Was I acting like an ass?
