@SevenDad: I was not calling YOU out. I was making a comment about one post. I have learned it the hard way that on an Internet board humor is a tricky thing. Something one thinks is funny can be easily read as snark by another. I’d stay away from jokes other than self-ridicule or trivial things like laundry. But I have no problem apologizing for not being a good sport.
On a serious note though, I think that whether a school acknowledges it or not (or in what ways to acknowledge it), they are all looking for nice kids for their boarding community in particular. While the bigger challenge is to keep them nice, a good starting point is to try to not admit not-nice kids. As parents, we all know what a difference it is to try to educate a nice kid and a kid who has already demonstrated aggressive and other types of behavior problems.
