Two young adults from Seadrift, friends since toddlerhood, ran into one another on the sidewalks of New York. The odds against that must be HUGE.
A friend of mine who was in the Army serving in France during World War II was walking down a street behind enemy lines when he heard someone say "I sure am tired of this, I wish that I was back in Texas." So my friend who was from Texas himself, found the person who had made the statement and discovered he was a friend from his home town; they hadn't seen each other since their high school graduation.
That was over 60 years ago and I guess the world was a smaller place then too.
