In the first sentence of this passage, the author conveys a sense of happiness, in her mother's happiness. However, this viewpoint changes in the second sentence, and changes to a more conceding tone; she is coming to terms with moving and "accepts she must live with her mother". The third sentence of the passage takes the viewpoint of acceptance and understanding of her own fate. This viewpoint falls in the fourth sentence however, as the author conveys the tone of sadness and longing; she's having a "hard time" and "longs for her old friends".
