The episode is the one where they decide to do something they always wanted.
In this case, Jack decided to audition for Broadway show. He is on the stage, and senses he is failing and his dream is fading. That is exactly how I feel.
I lived with my dream of earning a few pounds from writing stories for so long, the dream became my life. And now, I stand on the stage and like Jack, I find myself wanting and the dream fading away.
In October -- unless things change and I don't expect them to -- I will exit the stage and return to the wings. I will write, but for friends.
Anybody wishing to find can, I am on line at various venues.
