Before Sunrise & Before Sunset Book by Richard Linklater

Before Sunrise
An American tourist, Jesse, and a French student, Céline, meet by chance on a train from Budapest to Vienna. They feel an immediate connection during their conversation and Jesse convinces Céline to get off the train with him in Vienna to spend the night wandering the city. With the understanding that they will likely never see each other again, they share stories, philosophies, and their vulnerabilities, falling in love over the course of the evening. The film ends with them parting ways at the train station the next morning after agreeing to meet at the same spot in six months, without exchanging contact information.
