I think it is bandwagonning.
Does any woman on this thread really need to be told that, if you feel threatened, it is a good idea to go to or stay in a well lit area with other people, preferably woman, around you?
Good grief, I sound like my mother!
I remember taking the train home with her after a day out in London and being told we had to walk all the way to the ladies’ carriage at the other end of the train as it was dark and late.
Or am I misremembering? Maybe it was just finding a carriage with other women in it (safety in numbers)? Did they still have ladies’ carriages on the last train from London in the early eighties?
