You should never “take on” the lawyer who is asking the questions, remember, this is their home turf, so they are likely to feel much more comfortable in the courtroom and in our experience, Judges invariably insist that the lawyers behave with impeccable manners towards witnesses.
The Judge is also there to protect you if he or she thinks that a lawyer is being aggressive, or if it looks like a lawyer is unfairly trying to trip you up.
Don’t try to think where a line of questioning is leading, similarly, don’t try to work out whether your answer to a question will help one side or the other, in a nutshell, just give straight and honest answers to the questions.
One final thing… never – and we mean NEVER! – be rude to the Judge.
