(RURIC) HANGING NIECE

I was with my mom, my brother and his family. We were in his car, heading somewhere. I sat on the back, next to the window. After a while, I realized that my 5-year-old niece was hanging from my window (with the car running). I was like “WTF?!“, but everybody told me “Oh, it´s OK, she likes to do that all the time.“. They said so trying to explain me her behavior because I don´t really know her that much, but for me was just stupid and irresponsible. I got really mad and started yelling at them “You are all a bunch of assholes, how can you let her do that?!“. Suddenly, my brother pulled the hand break up, I thought my niece would fly because of the abrupt halt, but she didn´t. Then, he said “You see, nothing happened.“. That made me even crazier, I started cursing and shouting. My mother turned and told me “Besides, there isn´t enough room in here“. I got out of the car and started screaming at her “Are you happy? I´m out now!“. She replied she did´t mean that, so I got back in the car, starting to swear again.
