At least one problem is that Bob posted a question that a number of people decided was a troll, and so they jumped on him--he has a tendency to make short, stream of consciousness posts, and people have misunderstand a couple of them, as well--not to worry, though Bob--we all have that problem at one time or another--Not like I should be speaking for him, but I do want him to know that he's OK by me--

And if it is any consolation, Bob, I go through times when I have mixed feelings, too--
