I read about kids taking selfies on a visit to Auschwitz with their school last year... That settled it for me.
I work with younger people who have to be told - and constantly reminded - that you don't text and take messages during a meeting with your boss. How did we even reach that point?
Looking at the way we have "evolved" the last 10 years, I feel nauseated.
Progress really does a great job reconciling me to mortality (mine and that of others).
