Exactly what I needed, thanks for the interesting and informative reply.

Thirty six, and you're an old crone! Yes, thanks for reminding me; attitudes and conditions are an important factor even if you're one, because of age, they lavish attention on, and glad to have been reminded of it. I suppose it's because there's so many of them. Thirty six, is an age when certain assertive career-minded Western women turn their minds to anti-natal matters, while Chinese old crones of the same age are not China's priority. Mine is still 22..but even so...

I keep telling her that I'm too old-but she has a good answer "it will be something to remember you by" We shall have to see if I can rise to the occasion; lie back and think of England I suppose; and how much it will upset my nearest and dearest there.....yes, think it could be worth the effort, hahaha.
