Is Alan’s memory of real people or has he shaped archetypes, models of the people represented in his story?

The father-son relationship is a major theme in this play. Alan's whole life he's wanted to come live with his dad, who his mother didn't want him to live with. Once Alan arrives his expectations are met with the reality of who his father is: a womanizing, demanding, selfish, assuming person. The same man who left him and his mother, and abandoned his mom when she had a stillborn child by being out with another woman as she gave birth to a dead child.

As a result, we see that Alan's memories were veiled by the man he wanted his father to be.... he was chasing a deam. The reality did not live up to the dream.
