That makes sense. I tend to roll out the "Sorry about that" in situations like that because apology can be used to signal more than just sorrow or guilt--it is also a widely accepted method of disconnecting from a conversation. Just because someone surrenders doesn't mean they agree with you. Really, though; the apology isn't the gist of what I was trying to say. The gist is that the parent poster was in no way obligated to stand and take that lady's entire retarded rant.
