Answer:
A person has to play multiple roles in a society. For playing these roles, the actions and rules followed at each different location are not similar.
For example, at home a person might follow rules such as getting up early, making healthy breakfast, going to bed early at night.
At school, the same person might follow rules such as never sleeping in the class, maintaining discipline, respecting his teachers.
At work, a person might form rules such as effective interaction with colleagues, working hard etc.
Each place has separate rules because we perform different tasks and play different roles in each place. Our rules change with the change of place and tasks.
