I have sympathy for some of what you have said here Walter. Women with status also have to cope with men coming on to them at work, even if both are in relationships. If it is frankly sexual (as opposed to someone having a bit of a crush), the only way to deal with it is to be straightforward and say that you are happy at home and, frankly, not interested, then carry on professionally. That message will find its way to other people who might have tried it on - but sometimes it takes you by surprise and you're flummoxed! Hindsight is all very well.
Peter Hitchins is an anachronism.
Rhiannon, kudos to your daughter for reporting a fellow pupil for sending porn to her on her 'phone (think it was 'phone without looking back at your post). That's the way to do it and I take my hat off to you, she's a chip off the old block.
