Well, my kids didn't look like that...but they have been known to beg teachers not to call me. 
When I was in 2nd grade (which was around the early 70's) our report cards had two sections on the back. One section contained a spot for the teachers to make comments for each semester. The other section contained a spot for the parent to sign for each semester. This may be common even to this day. I don't know. Anyway, one semester my teacher, Mrs. Lewis, put the following comment in her section:
Chuck is a good student, but he has a problem with his conduct and tends to disrupt the class. On the bus ride home that day I read the comment and knew that no good could come of it. When I gave my dad the report card my prediction was proved correct.
The next morning I noticed that it took dad longer than usual to sign the report card. On the bus ride to school I pulled out the report card and discovered why. Above his signature he had written:
I have had a talk with Chuck concerning his conduct if you have any more problems please let me know. Now personally, I wouldn't consider our encounter a "talk". The belt made some sounds. I made some sounds. But I don't think there was really much actual talking. Regardless, Mrs. Lewis didn't have to worry about my conduct the rest of the year.
