The document describes a group of friends - Jessamyn Miller, Loretta Neal, Aseem Singla, Charles Hannon, and Soma Hannon - waiting for and riding the bus together. Aseem enjoys chatting with Loretta on his usual bus route. When they want to signal the bus, they press the "I BUS" button, which lights up a heart symbol on the driver's dashboard.
