Yes, It is also called playing a role. But it can be a real
role, as real as you want.
For example, If you are a General Manager, you have to behave as
one.
When at home, hey, you are either a mom or dad. As a daughter or
son, you also play another role. When with friends, you are not any
of these roles, you relax and be friendly.
There are many roles we take on in life. They can be very real, or
some people can fake it, Then it becomes a mask.
It all depends what you want. But we all play roles, real or
fake.
