Coming home, I was sat next to the guy with Tourette’s Syndrome. At least, that’s what I assume it is; I’m no expert. He’s often travelling either to or from Davis Square. He sits and basically babbles whatever enters his head. Sometimes he tries to read a book or magazine, and you hear bits of the text incorporated into his vocalizations. Tonight it was mostly unintelligible; if it was a foreign language, it wasn’t one I recognize.
Sometimes he can clear a radius of two or three seats around him. When I failed to move, he moved a seat closer; perhaps hoping I’d try to strike up a conversation.
