Pearls of Teacher Wisdom

I was out of school at a meeting late last week, and another--far more seasoned--teacher covered one of my classes. 

I saw that teacher in the copy room this morning.  "So that class I covered last week," he began.  Little good ever comes from copy room conversations that start this way.

"They told me how hard your class is," he continued.  "Keep up the good work."

He's well-seasoned for a reason.
