How can peoples lives and interactions resemble actors playing roles?

People will play a part they believe will get them to where they want to be, despite if the part they play isn't who they really are.

if you are an aunt, uncle, sister, bestfriend, mother, doctor, dentist, vet, artist, ect. If you are one of those things you play the role/part that status has. An actor plays a role that has a status has and resembles what that status is supposed to be like or do.

like if an actor portray's the status of a mother, their role is supposed to show you what that status is supposed to do. Examples for that would be nuturring, caring, and keeping after the children
