Awww.... how sweet....I teared up....great job:)

Awwwwww, we have a little T in the house! How sweet ;)
I bet he has that same sparkle in his eyes :P

Well, for a second there I thought you were a father. :)

Without reading the note, I thought this was about a man who has lost his wife, whether naturally - death, or perhaps, through divorce. And it shows how he loves his son dearly.
The person spoken to might be a new lover and he has finally found someone who did care for his son, assuming his past wife was someone who didn't.

After reading the note, though, I found this write much deeper than I thought. It seems like you've built a barrier, metaphorically speaking, around yourself. Perhaps it was something due way back when you were a child or something that grew overtime.
I'm sure there will come a time when each of us would find that "someone."

Beautiful piece.

Moving and thought inspiring.
