Equally important as observing teenagers this week is engaging in conversation with them. Ask them what they think of Robin Williams' life, work, and death. Share that suicide is one of the most common forms of death for young people, and ask them if they know anyone who has ever talked about taking their own life.
All we really need to do is watch a teenager playing a video game -- trance-like and oblivious to the world around them -- to know that entertainment, in every way shape or form, can change the way we think and act. Personally, I found the deepest meaning of this concept last summer, while visiting a filmmaker for a piece I was writing on him.
