Really?
1) Car drives up to your kid, says that he is a friend of the family. Then he rattles off the above information to prove it. How many times more likely is your kid going to be to climb into the car with that person.
2) If you let your child answer this questionaire have you passively set a precedent for further questioning.
3) Would you like your kid to be graded based on answering questions of a personal nature. If you do not say "NO" to this what else won't you be able to say "NO" to in the future.
4) If the police were asking your child these and other questions at what point would you say, "Sorry, you are conducting an illegal interview without a parent present. Give me my child and get a search warrant if you want such information".
5) If you passively give consent now at what point in the future will you be denied the right to plead the fifth in a trial if such questioning provides information leading to a charge?
Come on people, you can do better than this.
