Nutty and sad. (Even if my son were a loser — and this man’s son clearly is NOT one — I would never stop communicating with him.)
Needless to say this particular client and I do not have conversations concerning anything but very basic business issues.
Made a comment one time about dropping him as a client because of his very far left position on everything. One of my younger employees suggested that I don’t, but increase the fees we are charging him and smile when I deposited the money in the bank.
