I ran into my wife on the 125th St platform!
I was transferring from the 4 to the 6 and she was transferring from the 6 to the 4. I was exiting the train door that she was entering.
What luck! What a delight! We both squealed in delight and hugged each other. What a small small yet ginormous city we live in.
Then of course, she texted me about the experience: “Humphrey Bogart voice: ‘Of all the subway cars, on all the 4 trains in New York City…’”
