The guy is standing very close. Too close I felt. I put some distance between us. I see another young girl come and stand next to him. He obligingly makes place for her. She doesn’t know Uncle likes young girls. I call and warn her about him. She comes to stand next to me, giving him evil glares. Soon all the women had alerted each other that Uncle was a lech and all stayed away, keeping a safe distance. Men around us pretended not to notice what was going on. That guy got off the bus on the next stop, almost 15 stops before his destination. Speaking out works.
And to this day the most satisfying sound from male lips happens to be that ‘Ouch’ in the dark movie hall.
