I see - probably based on some scientific research into lived experiences of being raped every single day by the male gaze. I am glad I have no boys because I would have had to teach them the art of steering clear of all trouble by gazing at an imaginary spot on the ground whenever you're in public, like every other smart man on earth does to stay out of trouble these days.
P.S. also, strapping those knees close together to give every other passenger enough space to do their make up or comb/tease their hair.. lol. I honestly want to try clipping my nails or shaving my face one day on a train just to see what happens.
