One day my oldest son, at the time a kindergartner, came home distraught.
Eventually, my wife and I were able to coax out the whole story. He said he'd done everything he was supposed to do: day after day he was doing his work in class, helping others, being a good citizen, and everything else his teacher asked. He'd been a great line leader, a great tablemate, and almost always raised his hand before speaking.
Sobbing, he couldn't understand why the teacher just wouldn't ever change his card to orange.
