So one by one they all left her. Alone, sitting there, wondering what she would do with herself. And they didn't give her hardly a thought nor did they notice one bit how much she dearly wished them to stay. For as it is often said, people think often only of themselves. And of course, this was exactly what she was doing at that very moment. She was always on her own mind. Her concerns, her misfortunes, her trials, troubles, tribulations, her well-being. She was quite self-centred if one stopped to think of it. But no one did, because everyone else was, of course, busy being just as self-centred as she was. As they left, one by one, she waved goodbye and sighed, settling herself down on the couch, waiting for the next to leave and waiting to get back up off the couch to wave and say goodbye to them when they did.
And of course, they weren't everlasting and before long they were all gone and she really was sitting on that couch all alone, wondering when the first of them would come back, thinking only of what he or she would like to eat or drink and not in the least about how she might have been while they were gone. And in the end she didn't mind so much because she was just as self-centred as they, and she understood thinking that there was a need to look after oneself.
