To start off, you must ALWAYS side with Mr Moncreiff, you must never betray him and follow by his word. If he tells a tattle tale you mustn't object, ever. Mr Moncreiff likes to know that he has trustworthy back up and a man of trust. You must also cover for all his mistakes, he must look sharp socially and physically. As I say you must be on Mr Moncreiff's side, you musn't become to attached to one. He likes his space.
If Mr Moncreiff asks on your opinion on anything, you don't actually say what you thought of the subject. For example, if he asks on his piano play, you say it wasn't polite to listen. Giving your own opinion isn't very necessary therefore it isn't needed as it could be taken to an offence.
Some basic things to get on with though:
1) Be clean and dress well
2) Mentioning marriage positively is very arguable with Mr Moncreiff, you don't want to get on the wrong side of him.
3) Agree to what his opinions tell you even if you don't believe in them, pleasing him keeps you on the right side with him
And finally, forever cover up for him, if he's in trouble you back him up, but do try not to get yourself in a twist and get into trouble.
Sounds confusing, yes, but you shall get the hang of it.
Yours Sincerely,
Lane.
