Teachers

I used to have a teacher like this, but she didn't do it on purpose. I
remember she would give me bad grades for doing what she told her and
afterward would say she liked the way I was doing it myself before I
listened to her. Then say I should never have listened to her. It was
an incredibly enlightening experience. This story just made me smile
and remember the best teachers I ever had.
