As Philip had feared all his life, the truth does out.
He had tried to keep a lid on things, to keep his true character under wraps, but to no avail. Seeing how life treated his parents, especially his mother, he was desperate not to go down the same road. Life is what you make of it, how you carve it. And Philip wanted to pick his life up by the ears and give it a darned good shake. He refused to accept whatever chance happened to throw his way.
However, to achieve this Philip knew he had to change his essential character, because it was his character, his traits which he had inherited from his parents. And look what had happened to them. They got nowhere. They scrimped and saved, they argued and fought, they lied and cheated, and finally they bashed and murdered.
Well, one of them did.
