Re: Oh man, I feel his pain
The company I work for has to deal with the education sector and teachers are the worse. Most believe it is always someone else's fault and never their own, will blame their mistake on something having not been explained or documented well enough or it not working as they think it should. There are a few who will be gracious and apologetic in accepting it was their mistake. Most just leave in a huff while retaining the belief in their own superiority.
