Well, at least you're not a complete barbarian then. I suppose that's the first step.
Now I'm going to need you to change into your finest shirt, your fluffiest trousers, wear your fluffiest hat and put in this:
Now stand up straight, chest out like a man, good sir! Stiff upper lip, very important! I don't want to see it so much as wobble! Now go stand like that in the street and practice ignoring the filthy commoners. When you've done that for a few hours, go over to your friends house and discuss the merits of various wines, historical figures or something else that's educated and interesting. Laugh at silly knob jokes for precisely 15 minutes, then switch over to labelling various words as either "woody" or "tinny" sounding words. Be sure not to let the caribou nibble at the croquet hoops, if it seems to be going for them, use the double barrel your manservant carries with him at all times. Now request an absurd cocktail and finish off by gently ordering Mr. Music to play.
That's lesson one.
