I really like Jesse's observations about builders.
"Unprofessional" was probably too strong a word and I knew it when I wrote it...shouldn't post when I'm tired.
The teacher's actions and words shows what he believes to be his reality. Would consistent, ongoing, gentle, kind prodding help sway his belief? (so as not to have him feel defensive)
If he's been using this approach for a long time, it's unlikely that his opinion will be changed.
I like the idea of setting a date independent of him and just moving on.
Perhaps this guy will respond well to a classic snow job: set your own date, go along with what he wants, and ignore the rest. Your daughter could use the experience as a lesson in the a) cockeyed ways that the world can work sometimes and b) how do deal with the lunacy constructively.
