I agree vampirequeen that things have definitely changed since we were young. On the bright side, young people don't need to learn to negotiate the minefield it could be fighting off the kind of colleague who we used to say should be fitted with four-wheel brakes.
Everyone now yells "sexual harassment" at the slightest provocation, which is all right, but compliments, flirting and remarks that brightened our day, such as " you look nice today" are being thrown out with the bath water.
Some years ago (only four or five) I was watching the last night of the proms on TV and when the young female violinist came back on stage for the second half of the programme in another and much more becoming evening gown than she had worn before the break , a man called, " I like your frock!" Is this to be considered unacceptable behaviour today? I hope not.
As to what sexual assault is or isn't, in Scotland at least, I think it is the term used to cover any attempt at rape, that was thwarted. The procurator fiscal's office would also use the term "sexual assault" if it was open to doubt whether the woman actually had been raped and to cover any other of what Scots Law used to call "lewd behaviour" that the one party either was forced into doing, or managed to avoid by protesting or defending herself (or even perhaps himself!)
Like all the rest of you, I have no intention of condoning rape, sexual assault or those in positions of authority or with a duty of care who proposition those working for them or under their care, but it's a sad world if we can no longer flirt light-heartedly.
