I have a theory about Thom Pain play

After Thursday class i don't know why but i have this weird feeling that it's either about his life or someone thats he knows. Why i think that because the way he was talking about the little boy in the book it's like it's his childhood but even thought he talking in a third person it made me feel he didn't want people to know it's his life he is talking about because maybe he doesn't want people to think he is weird or something is wrong with him. I hope my theory is right or at least close to it.
