The teacher seems to be upset by something that probably happened to her when she was a kid. Maybe 'her' parents lied about Santa, and now she sees' this as her job to right the wrongs of parents, by telling their kids the truth about Santa. Who cares if kids believe in Santa, they eventualy learn later on in life that it is just a story, but a nice on at that. I don't believe in Santa, and my kids know that we (the parents) bring them gifts, not him, but that's the way I was brought up and thats how I'm bringing up my kids. But there is 'no way' I would ever tell a kid(s) who believes in Santa, that he's not real. That's for them and their parents to deal with, not some pissed off person who dossn't understand what it's like to be a kid. But that's my opinion.
