A young smartly dressed woman gets on, concentrating on her phone call. The bus pulls out before she has time to mount the stairs, and the motion throws her to the side, her bag swinging and bashing the passenger behind her. Fifty. Nine. To. Streatham Hill. She climbs slowly, letting everybody know about the important things she has done today. Then drops into the nearest seat as the bus brakes at the first set of lights. “Did you remember to tape Eastenders?” Puts a laptop on one knee, opens Microsoft Excel, a page full of graphs. Continues call, continues describing her brilliant sucess with the Weight Watchers account. More passengers board, one indicates to the empty window seat beside her. She turns to let him through. Drops the computer. “Fucksake”. People chuckle.
