We can chalk it up to agreeing to disagree. I don't call the act of parenting foolish...it's our decision as parents to raise our kids the way we see fit not the schools decision. I feel more people should be active in theirs kids lives and that includes what happens at schools.
I do find it ironic that teachers and educators always say parents should be more involved and when they do we get labeled as foolish.
If the guy was an upstanding person I would not have a problem with him speaking to my kids but he is the bottom of the barrel and I'm being nice.
