Somebody sit next to me. Please!

Have I complained about the transportation here yet? When you first arrive in Japan the public transportation is usually one of the first things your amazed by, thousands of rushing people squeezing into small spaces. But I think as I have been here for a while my impression has changed, mostly because of the fact that no one will sit by me. Recently I lost my bike key and have been riding the bus to school which is completely inefficient and uneconomical but nonetheless an experience. Most mornings after a few stops the bus starts to fill up. I am usually one of the first stops so manage to get a seat, but a lonely one. After the bus fills,people squish into every crevasse of the bus except the perfectly comfortable half of the seat next to me. Aww, the life of a Gaijin. Won't anyone sit by me?
