My first Public humiliation of life

So , I went to a place ( I don't wanna name it after everything that happened ) . Okay so this place was nice like very nice . It was the perfect place, I always dreamed of. Like ,where people follow rules and have like great civic sense. Its peaceful, no horns nothing. So , my parents went somewhere. And I was left there with my sister , brother and a cousin. And mind it I was the eldest. So we were at a place where u have a lot of guards. And there was a area where people were sitting. And we were roaming around at that time . And after sometime we also sat there but I didn't realize we were the only ones sitting at that time . So the guard comes up and says that sitting is not allowed . We got up . But my sister kept bitching because two other people were still sitting at the other same spot. I told her maybe there are locals or smth and its their matter if they r not following the rules and u should follow them and have some etiquettes, manners , rules . And she is the kind of person who never wants to follow rules and I don't know how to describe because the words coming into my mind are too harsh to describe your own sister. Like a 'dumb rebel'. And she sits again . And when the guard sees it.....she comes. First she tells the other man who was sitting . And by that time my sister came to me . And the guard starts started shouting , like heavily shouting at both of us or me because my sister was turning her head opposite to her like a 13 year old kid full of unnecessary attitude . And oh my god ! I stood there listening to the guard. And people were looking, turning their heads 360° . And I freezed ( mentally ) . Yeah ! I know thats not how you survive in the outside world. I didn't even say sorry , because idk , its was my sister who was sitting not me . And I had gum in my mouth and I was subconsciously moving my mouth , which might have offened her more. Only I know how I controlled my tears after that. Yeah it was a memorable trip! Thanks to the guard and thanks to my zahill sister .. I am sorry, I am furious and I can't control it.
