Again...?

David, you know I've always had trouble connecting with people.

I just can't tell what they're feeling, what they're really thinking about.

My whole life, I've felt like I'm watching the world from the other side of a window, and I just don't know how to pass through to the other side, where everything is effortless.

David, I need to know.

How do you know if it's too late to change? How can you tell if it's still possible "to begin” again?
