I guess "upthread" is this [0]? If it is, there's a critical part of my comment that you left off in your comment; namely the part of the comment where the speaker addresses the hypothetical posed. This is a part that I included in my hypothetical Mother's Response:
> "No. You would not be required to do so. However, there are presently no known obstructions between you and the door to your room. Go to your room now, lest I find you in contempt of Mother."
Your comment omitted the explanation -thus ignoring the hypothetical- and went directly to analysis of the situation as it currently is.
Context is everything, and the person to whom you were speaking was not likely a child and wasn't asking a series of hypothetical questions in order to put off some unpleasant task. Therefore, the lack of explanation in your comment makes it substantially different from mine and -because it lacks the useful components- not really productive. :)
