Okay - so a friend told me the other night that there is a course for future CO's wives to go on to learn how to be a CO's wife whatever that means 
I thought this sounded very strange so asked whether it's the type of thing about etiqette (how to say hello to the queen or whatever).
She said CO's wives should already know that anyway! I thought perhaps she's winding me up but she insisted that some of her friends are going on the course - some to have a giggle but others because they felt they should take it seriously.
So it right and if so, where's the course and what do they teach you exactly?
