What should I pay attention to when living with my sister?

Sister is not an outsider, but a woman! Live with your sister. If you are a boy, you'd better:

A, listen to your sister, what can and can't be done. My sister is older than you. When she teaches you, you must do as she says.

B, read more books and materials about how to improve their own quality, self-cultivation and manners, and constantly improve their overall quality.

C, pay attention to the dribs and drabs in daily life, such as not wearing indecent clothes, knocking at the door in my sister's room and so on.
