Page's family is a second-child family, and many plots revolve around getting along with his brother. There is a lot of space about the interaction between two babies. Peggy sometimes takes care of her younger brother, and her sister is an example for him to move forward. But more often, they play together like good friends, and occasionally Page will bully his brother, but this is normal.
In real life, there will inevitably be competition between brothers and sisters, but there is no lack of care. There will never be a night feud between relatives. Therefore, it is only a manifestation that an elder sister bullies her younger brother occasionally. This description, in our view, is the way brothers and sisters get along in ordinary life. This reality is also grounded, which is one of the reasons why it can be fired.
Nowadays, it is very helpful for children to grow up if they are accompanied by brothers and sisters. But they are inclined to national policies and have many only children, so they also envy the plot. Many only children are eager to have a sister like Page or a brother like George, so their childhood must be very interesting.
The definition of a good sister is more than just doting on her younger brother. Blindly doting will only become doting. And sometimes the competitive interaction between brothers and sisters is just another manifestation of love. Just like Peggy in the play, she is a very good sister.
