I’ve noticed that it is considered discourteous to respond negatively to the “How are you?” question. Perhaps, I am not feeling well. Perhaps I had a rocky night of sleep or something unfortunate has happened in my life. But it seems the only answer allowed is “Fine, thank you”. I’ve also been chastised, oy! by my wife, that I had not asked her “How are you?”. I have started greeting people with Hello. Just hello.
