I had a brother who wouldn't speak to me normally for 7 years,
  outside of important business stuff. He never said why, except,
  "You know why".

  Finally I figured it out: I said something to someone I
  shouldn't have. All those years, he assumed I knew EXACTLY what
  I did.

  I didn't.

  Now, here, in this little forum in a far off corner of the
  Internet, a man is telling me, "I'm waiting for you to answer my
  question".

  But he won't tell me the question.

  *sigh*. You'll just have to wait because, I have no idea what it
  is. tongue emoticon

  It might just take me 7 years to figure it out.
