Thanks duchesse - I'm sure you're right, and I have mentioned it several times over the years - I'm just not sure if I have enough. Perhaps feeling that mentioning it a few more times before it happens may be an idea 
Hopefully her PHSE lessons have been better than mine were, although mine were some help even in those days ! In fact she was talking to me about them (PSHE lessons) this evening - didn't say much, just that you just sit there and listen and try to avoid answering any questions by taking an intense, sudden interest in your pen if teacher looks your way ! So, all sounds very understandable 
Would be good to feel we're making progress with each generation though. Want to help her with growing up all I can. I think I'll see about ordering a book or two on-line tomorrow.
