A generation is united by much more than simple demographics. The movies we watch, the music we listen to and the books we read also define who we are. Our generation grew up with Robin Williams. He is part of our cultural pantheon. We asked people what they would say to him in a final goodbye. The people we spoke to came from different backgrounds, but they all reacted the same when we mentioned his name. Some called him "Genie," others called him "Captain," but everyone said thank you.
