Sigh, you obviously don't want to reach some kind of a compromise.  Are you really unable to grasp the concept of summing up something, which can't be summed if it doesn't already exist?  I'd say that you perfectly understand it, and that you're just pretending and trying to annoy me to the point of giving up.  So, why didn't you respond to the thrid-opinion request?  Did you actually go that way to silently boycott it? —   |
