Lovely, sad and on target, Nicole. The more modern we get, the more trapped inside our heads we are forced to live. Must it be this way? Why is it polite to "not bother" people on the train or elsewhere where many are hoping to be bothered? What are we afraid of? There are in fact very few serial killers but we are always on the lookout for them. Be safe but make eye contact. You might just make a friend.
