@ossobuco,
The problem is, BillRM is the one who doesn't know how to act in an appropriate adult manner. And GracieGirl did a fine job of calling him on the carpet for the way he's been acting.
GracieGirl shows far greater social maturity, and much better social skills, in her interactions with other posters than BillRM does, not to mention that her posts are better thought out, and considerably more coherent, and expressed in much better English than his are. And she certainly shows much better comprehension of what other posters are saying than he does--nothing seems to sink in, or register, or even penetrate, with him.
The irony is that he questions whether she is too young to be at this site when, in fact, he is the one displaying the questionable and somewhat inappropriate behaviors and behaving in less than a mature, adult manner. Her influence at A2K has been positive in terms of stimulating discussions, while his tends to be disruptive, provoking needless unpleasantness and derailing threads. If he was smart, or had any sense, he'd try learning a thing or two from her.
