Friends, Please permit a correction to the previous post. Autocorrect changed the word "haven't" to the word "have" in a way that changes the meaning of a key sentence. This sentence in my post to Terry should read: "I certainly have NOT indulged in the kinds of sharp ad hominem attacks that have typified your behaviour when you become irritable."
