i heard this funny story the other day. this woman owns a coffeeshop on the main road of shibata which runs perpendicular to the train station. it's quite a popular road with people walking up and down it all day long. so this woman often sits in her coffeeshop staring out onto the street at all of the people walking by. she remarked on this particular elderly couple who she often sees walking by in the direction of the station, with the old woman in a wheelchair and the man pushing her. then, about 15-20 minutes later, they walk by again, in the opposite direction, with the man in the wheelchair and the old woman pushing.
