    <p>Dear Seah,</p>
    <p>no, we really can't, since we don't understand what you're doing.</p>
    <p>Please deliver an overview of what you are trying to implement.
      In my experience, a drawing (just a quick drawing on a piece of
      paper will do!) is often very, very helpful at illustrating
      complex systems like what you seem to be doing.</p>
