P - Parents, if you meet them, will ask you loads of questions. Sometimes their requests are out of your control. If you don't know how to answer them, be courteous to them and direct them to someone who does.
Sometimes they might get snappy, wonder why you don't know or argue with you, but it's best to just direct them to someone who can help or calmly escort the parent to find someone who can resolve any problems.
