Answer only the question asked. Do not volunteer additional information. If you don't remember the information that you are asked about, say so. Answer the questions verbally. Look at the jurors and speak to them when testifying.
Jurors are ordinary people, like youself.
They consider attitude, facial expressions, and body language when evaluating testimony. If you don't understand or didn't hear the question, ask that it be explained or repeated. If your answer was not correctly stated, correct it immediately. Never attempt to talk to a juror about the case or any other matter while the case is being tried. This includes chance meetings during recesses, in hallways, at lunch, or any other place.
