Inconsiderate commuter

Back when I was pregnant I worked 12hour retail shift my bump was barely showing even up till birth but one day when I was travelling home I was on the train sitting on a NORMAL seat, this elderly man boarded the train on the next stop n did not appear to want a seat, he went to the door n leaned on it. A few people offered their seats but he said its only 2 stops n its easier for him to stand. Suddenly this girl probably 15/16? Came over to me n told me to stand up n give the uncle my seat when there was a young boy probably 14 since he was wearing uniform, sitting on the reserved seat. I told her I am pregnant n she said it doesnt matter as long as I dont look pregnant I should give my seat??? The uncle then scolded her n said that he doesnt want to sit n she should mind her own business, she then came n argued with me about having to give up my seat n so I pulled out my KKH booklet n told her “go f*** yourself” she called her mother n cried. Before she got off the train she “scolded” the uncle saying that he’s ungrateful 🤦🏻‍♀️
