GIR cross-examination

Here are my standard rules for my witnesses on examination by opposing
counsel. They are worth learning well ahead of time because they can be very
difficult to follow. Memorize these and we'll do fine on cross (assuming we
even get any questions).

1. Listen carefully to the question.
2. Answer only that question; do not volunteer more.
3. If you don't know for sure what the answer is, just say so.
4. If you cannot answer a "yes" or "no" question with "yes" or "no," say so
and explain why.
