In this case the formation of her own identity is being affected by two strong but opposite influential forces. But what if she were born in a different country with another religion, or with a family with a different culture, she wouldn't be the same person as she is. This is why your identity is built by putting together all these factors, and because you do not have the gift of choosing where, when, how and who you born by, then you are not free to make your own identity. Sometimes people try to choose their identity because they want to belong to something, whether it's a club or a gang, it gives them something tangible they can label. Where people get lost, is when they tend to follow trends, giving way to imitation. People try so hard to be what they are not, that their true identity never surfaces.
Once you are able to identify yourself, with certain sets of values and aspirations, what makes identity problematic is the difficulty you have in keeping it authentic. In The Complete Persepolis is evident that Marjane does everything possible to integrate and be better accepted in her new life, "I didn't like to smoke, but I did it out of solidarity." "Then I imitated their laughter"(192) It becomes nearly impossible to be authentic because depending on the context or situation that you are placed in, you are essentially required to adjust your identity to fit those expectations. When a person is with their friends, they behave, talk, perhaps even dress in a certain way. When they are with their parents, their identity changes. At work, at school, everywhere they have to change.
The authenticity of your own identity is what affects your freedom of choice. Even though it is not possible to be too authentic, there are people with a strong personality who are not afraid to share their thoughts no matter what others may think or say and the social problems they can cause.
