The girl on the 8:15 train with the red book.

We’ve sat across from each other for three weeks straight. You always read the same worn-out copy of 'The Great Gatsby' and you always get off at Grand Central. Today, you caught me looking at you and you actually smiled. My heart did a literal backflip. I wanted to say something—anything—but I just looked down at my shoes like a coward. If you see this, I’m the guy in the blue jacket. I’d love to know what your favorite chapter is.
