How does Charlie feel at the clinic? How much do you think this brings Charlie and his sister closer together? How so?

Charlie drives his sister to the abortion clinic and sits in the waiting room while she goes through her procedure. He decides to sit in the car because he is about to start crying and does not want anyone to see him break down. While he is sitting in the car, he thinks about all of the times his sister has changed - how she became a young lady and how she began to realize she is pretty - and he wonders about how the abortion will change her. His sister leaves the clinic and finds Charlie smoking, and she threatens to tell their parents. They both know that this will never happen, and they start laughing. Charlie can't stop laughing the entire way home. They return home and tell their parents that they have been at a movie for the afternoon, and at the end of the evening Charlie's sister thanks him for everything that he did. They tell each other they love each other - a rarity in their relationship.
