Have enjoyed reading the exchange of comments and the obvious good humor on this forum. I would like to participate when I have something to offer.
I came across an interesting magazine article recently and would like to offer this item for your consideration and comments. I will pose it as a question and see if it merits any discussion.
Is the following sentence properly punctuated?
"He is a good friend of Robert's."
This may be too basic a question to raise for this level of scholarship--if so, I apologize and will restrict my future participation to commenting on other people's posts.
