The Intersection of Two Worlds – Interesting people seem to ride the train at Fullerton California. Here, a couple who choose to live in different time and place, interact with the chair car attendant on Southwest Chief, arguably from another - hence the intersection of two, distinctly different worlds both coexisting simultaneously. Further, which of the two worlds constitutes the "current" time and place would depend on which world the observer that is making the observation is currently situated, since observers from both frames of reference both would claim to be in the present time and place if asked the question independently.
