I’m afraid to answer with down answers like, “How am I doing ? A family member died, my knee has no Cartilage left and hurts, and my 401k is down fifty thousand. That’s how I’m doing!” Haha. I can see the other person cower, and me saying “Oops, sorry.” I think how are you doing is tantamount to saying, “I care to ask but I don’t really want to know.”
