Try being unbelievably considerate and complimentary to them. It worries them something rotten. It is a form of turning the other cheek, but sarcastically. Spend your thinking time cooking-up ways to be nice, BUT.....

I once got round this by describing a self important beard grower as hircine. He thought it was a compliment!

(hircine is not related to hirsuit, it relates to having the qualities of a goat, cf porcine & pig)

A week later you can drop the explanation into converstaion but these things have to be rehearsed and you have to pick your moments.

Have fun.
