I can't really say anything that hasn't been said already but I will give my 2 cents anyway. I think he was wrong in initiating any kind of unprofessional conversation with you. If he wanted some spice in his life, he should have found it elsewhere, not with a clients parent. You just don't mix business with pleasure, especially in his line of work. Who knows how many others he's done this with, or how many have allowed him to take it further? Kids especially. People like this see when someone is stressed out or whatever and then take advantage of it by making you think or feel like they are helping you or are interested in you and then bam, he has you right where he wants you and can get whatever it is he wants. It just really worries me that a person like him is holding that kind of a position in a school.
