Hey Fred.....since you're throwing out old statements, let me give you one. "If you can't say something nice to someone, then don't bother saying anything at all" (falls under the category of having manners). Although I agree with you about self help and reading up on the subject/hobby and in the process of looking for something, you end up reading 10 other things you didn't know. Ok that's enough of me being on my high horses.
It is better to be silent and thought a fool, then to speak up and remove all doubts.
