I keep schtum; my parents would worry and can do nothing, and its no one else's business, except my wife and she is utterly normal and takes everything in her capable stride with no fuss or upset. True, I am not quite sure what others make of my, shall we say, occasional peccadilloes, but I am a forbidding character at 6'3, 105kg and an unsympathetic facial aspect, so that might be why it is never mentioned.
