So I was sitting in a 2-seater today, and the seat next to me was free. I was marking some exams and pretty much not paying attention. Then a lady got on the train, obviously very overweight, and sat down. Only, she didn't just sit down.... she also sat on top of my thigh and the force of it slammed my opposite hip into a metal sheet on the other side. It really really hurt. I said "owe" but she said nothing and looked away. She was really hurting me. The thing is... no one wants to be the person who says "hey, that isn't acceptable, please stand up". No one wants to be seen as discriminating. I understand she is just as entitled to a seat as anyone else, but if you don't fit, you can't hurt some one else in order to get your seat. Am I wrong? I thought she was very rude. I've got nothing against overweight people, but I do have something against ANYONE who imposes on my body and my personal space for their benefit.
