A friend was telling me of last year's "horror story" of her son's teacher who was really a piece of work. In describing the letters sent home to the parents they would go as follows....
" Next week, Dr. Smith's class will have a field trip to the museum. Every child in Dr. Smith's class should pack a brown bag lunch. All children in Dr. Smith's class must return the permission slip by Monday. "
The funniest thing in her tirade was the fact that all the kids had to address her as Doctor Smith when speaking to her!

Our kids did great last year, but we are automatically still on the list until they do it again.
It's entirely appropriate in an educational setting.
But now that she's a SAHM, I send her mail to her first name/lastname with no titles. It's usually just diaper coupons, nothing that requires formalities.
