It is theory speaking about people creating and playing social roles just as "server leader", "car mechanic" and go on.
Because of that people are creating own vision of world that is either forced on self or others.
Expecting people to play a certain role to became accepted by others.
By "entering into role" people aren't showing self but the type of characteristics that are being accepted under the role. It works even in dating world and so for that reason people doesn't love a person but rather the role that person is playing.. as example a "doomer" or "femboy".
This is also a main reason why most of relationships are falling off since that role cannot be played all the time by us. And so our true self is showing on and the people that "felt in love with us" aren't really interested in us but in the role we have played.
What about you? Would you prefer to be rejected by majority but be accepted truly by 2 people or do you prefer to live in ilusion of be accepted by everyone?
