Lessons learned

Lest people think MeTheSheeple is merely disgruntled over a current war, he'll suggest he can find humor in the tragedies of the past. Quoted in its entirety is the finest letter to the editor he's ever read, via The Boston Globe:

THEODORE SORENSEN, Jack Valenti, Henry Kissinger, and Alexander Haig were at the John F. Kennedy Library recently to speak on lessons learned about the Vietnam War (''Vietnam-era aides cite the lessons of a US defeat," City & Region, March 12).

When I go over a test, I occasionally ask students to show their work on the board. I would never think of inviting failing students to explain how they did a problem.
