Here, though I'm sad to do it, I have to censor words of praise. My son Sean had an assignment to shadow a public school teacher for a week and then write a report on how she had performed in class. An important part of the process was strict confidentiality -- the teacher will never know how she was judged.
Sean got very high grades for the report, incidentally, but he (typically) never got around to showing it to his mother and father. I found the report some time later when I lifted the living room rug to clean under it. Sean clearly didn't want the thing, so I pasted it in my notebook.
