I'm afraid the answer is yes, RL. On the other hand, if he doesn't know he's wrong, then it doesn't matter. Ignorance is bliss. One of the consolations of getting older is that, no matter whether right or wrong, an opinion is an opinion. I no longer profess to be right and I no longer try to argue the point with someone who doesn't agree. Politicians and diplomats when expressing an opinion use the phrase "in my view". That solves everything hehe.
And the good thing about being solo is that he/she can be as right or wrong as he/she likes and in the words of the old song, "ain't nobody's business but my own"
