Wordy Puzzle

I have broken the puzzle down into the smaller pieces and drew the diagram from the person who is speaking.

I do not have Brother and sister. That means, that man’s (Brother) father.

Is My Father’s son! Here, the son is a brother. My father is a father who is speaking. And that man is my son.

My Father=========My Father's son======== that Man

My Father=======me

 

Myself (I) am that man’s father.

My Son is that man.
