I want to apologize to MaryB, an unequivocal apology. There is no excuse for my rude and obnoxious behavior. Mary does more in a week than I do in a year. I have always read every one of her posts ever since she joined and I admire her work ethic, skill, and knowledge. She is someone to be admired for all she has done to help others and in making this forum a continuous success. Even if this were not the case, and clearly it is, there is no excuse for rude and obnoxious behavior. I hope my apology is accepted. I cannot unring the bell. But I can proceed in a manner that is constructive and positive, if only to demonstrate that I am sincere in my apology.
