I was raised never to point at things.  For instance, if I wanted some extra potatoes at dinner, I wasn't supposed to point at them and say, Gimme some more.  I was supposed to keep my hands at my side and say, Please, if you have a chance, would you mind passing me an additional serving of the potatoes.  In this way I passed much of my childhood, a delight to all of the other people at the table.  It was only years later that I realized that, pointing at various objects as I came into contact with them, might not be such a bad idea.  And so now, I am happy to report, I point at most anything in my proximity.  I point at the weather. I point at the sun.  I even point at the air escaping from my lungs.
