Now, that's what I would have said if they were asking questions prior to leading, but, you're still in a live auction. So, first of all, you don't explain your own bids in a live auction. Your partner should be explaining what you've agreed that your bids should show. Obviously, there is always lee-way for discretion. As I recently read someone quote on these forums: Basically, you explain what your bids should show, as you've agreed, but you don't guarantee that your agreements perfectly reflect your actual holding on this hand. Not that this necessarily applies in this situation. I can't really imagine why the player left the table. If you've properly explained your agreements in a situation, and fulfilled your responsibilities, your opponent has no recourse unless you've committed some sort of infraction. Of course, you should welcome questions, but at some point, they've got to move along or you're going to call the director to make them do so.
