What can be a true thesis statement in writing an essay for "My Oedipus Complex" by Frank O'Connor?

Given the fact that O'Connor's "My Oedipus Complex"
depicts one of the Psycho-Sexual Stages of Development, the Phallic stage, one can see
where the title and the story emerge from.

Larry, the only
child of his parents (initially), receives complete and undivided attention from his
mother given his father is away fighting in WWI.

Upon his
father's return, Larry no longer obtains his mother's undivided attention. Instead, she
devotes all of her energy to his father. Larry becomes very jealous (notated by Freud's
Oedipus Complex) and wishes to take his father's place in the relationship with his
mother.

Later, the arrival of a new child, Sonny, places
Larry's father in the same shoes Larry was placed in when he returned from the
war.

There could be many different thesis statements which
would define the relevancy of both the text and the use of Freud's
theology.

1. Both Larry and his father possess
characteristics typical to one deemed "stuck" in Freud's Phallic Stage. (How are they
characteristically stuck in the Phallic Stage? Examination of both Freud and the
text.)

2. Larry's mother is responsible for his inability
to accept his father's place in their lives. (Paper will examine Larry's
mother.)
