Don't tell them you don't care what they have to say even though we don't. Be less confrontational. Let them rant all they want if you can't get away. Thank them for their oppinion (without sounding sarcastic which will be very hard) and leave it at that. Thier feed back on your skills should be like water off a ducks back. Officials must be calm at all times, even though we have to deal with parents who know little to nothing about what it is we do. Just my 2 and a half cents.
