I am half think of writing a little 'piece' on what NOT to say to someone who confides in you that they have been assaulted.
It seems (at least from my experience) that so many people who are lucky enough not have suffered an assault are completely unaware of how psychologically damaging their words can be :(
Here are mine. All of these have been said to me and badly hindered my chances of recovery:
"Why didn't you [insert brilliant idea that it is now too late to do]?"
"Well, you were in a nightclub."
"Are you sure?"
"I think the thing to learn from this is not to be alone with a man unless you really know him."
"You should have known he'd want sex."
