"Pointing a finger" is NOT meant literallty. It means calling attention to something VERBALLY handfree. You do know that right?

As a child I was taught that pointing a finger was impolite. Did you hear that too from your parents? Now when you actually do  point at something like a rainbow or a flower or the sunrise or someone famous or anything/anyone else it is simply guiding not criticizing. When I or anyone criticizes a donjohn for example those who despise his being criticized incorrectly say "you are pointing a finger which means 3 are pointing at you". That's not true. That's complete bullsh** and a good example of folks using cliches that are meaningless. SIGH. There is no way out. We are in room with no doors no windows. NO EXIT.  Was it Jean Paul Sartre who wrote that pllay? At any rate we are stuck using nonsense phrses as if they are profoundly meaningful when they're not. It's like pointing out (not digitally) that the emperor is naked as a jaybird while folks who are mesmerized by him see him fully clothed in raiment befitting a king. What they see does not exist in realty. Thank you for your precise reply tom! :) I appreciate it.

I was told that, but I thought at the time that it was a silly rule.
