When It Comes Right Down to It, There's Nothing Like Adam Davidson's "The Lunch Date"
The answer isn't easy. Lewis and Aydin's book is amazing, as is Mark Long and Jim Demonakos' The Silence of Our Friends. Both of these are exceptionally compelling graphic novels and among the best books of their respective years.
However, if I had to choose, I'd go with a piece I've done so many times with my students: Adam Davidson's 1989 short film, The Lunch Date, winner of the 1990 Short Film Palm D'or and the 1991 Academy Award for Best Short Subject.
I could spend quite a bit of time here explaining to you the brilliance of Davidson's film and what its implications might be for your classroom. Just watch it, however, and be prepared to be absolutely blown away.
