"There's people around who walk up and down streets in order to be with themelves for a while - some stay longer than others. The dumb loners tend to be content and fight no inner battle to enjoy their own company. When walking with another replaces the long walks with yourself, and another's whole being trumps the company of yourself, your own company is rendered useless. So when the person leaves, their company takes your company from you, leaving sweet dung-all to walk the street with. This purgatory is called the back of her”.
