Realistic vs. non realistic

This play is full of things that are both realistic and non realistic its just important to be able to distinguish between the two. Originally i was using non realistic and unrealistic as synonyms and I thought that it was unrealistic that Tom would go to the movies every night since they don't release movies that often. Because of this I assumed that Tom was lying about what he did when he went out at night and that was a poor assumption. I feel like all the details in the stage directions make the play more more realistic. The setting seems very appropriate for the time period. Also I think that the family's situation is fairly realistic with the dad leaving and Laura's disability. The narrator is really one of the only non realistic things that jumps out at me. Obviously no one walks around narrating their life and in addition to this Toms "memories" include scenes that he isn't even in so how does he remember that?
