May I offer an observation as someone who feels like he is on the "outside" watching? If anyone thinks my observation is wrong or unwelcome, I'll take my lumps. I doubt that the people who complained about your manner of responding to Jo's original question were "attacking" you. I think they were just frustrated by your apparent arrogance, and your follow-up that they should learn how to ask questions the way you want them to be asked. They probably don't appreciate your self-appointed role as the designated grammar teacher. Wouldn't it have been simpler for you to just say, "I do (ha ha.)" And then follow-up with a real answer? I have to admit over the short time I've been a member of the club I have noticed that you, yourself have a tendency to censure people and make cutting comments when you appear to be tired of their conversations. I think your friends are still your friends. They just felt annoyed. No offense intended. :)
