I know I was certainly subjected to what I would now know as sexual harassment when I first started work, but at that time, it was just something you put up with.
I was, however, assaulted on a crowded bus many years later, and if anyone had asked me what I'd do if someone had done that, I'd have said I'd have shouted, screamed, slapped the man - something along those lines.
But when it did happen, to my horror, I completely froze. I couldn't move, couldn't speak, couldn't do anything - and even as I type this, I am filled with shame because of it.
