RSVP! If I trouble to help your homework and you never reply or react I will enter your name in a black book and not help you next time. I may do this if you let the thing drop before any conclusion reached. Don't tell us you have got the answer, tell us the answer you have got! - it is not always as good as you imagine - even when it agrees with the book.
