Wordy Puzzle

Word problems have always been a bit confusing for me and this one took me a while to think about. Since the words were confusing, I drew a picture to try to understand what is happening. 

Who is speaking?

I am speaking.

Who is "that man"?

That man is my son.

What makes this difficult/interesting?

This was difficult for me because there were no numbers. It was all words and we do not know who is speaking. The play on English words and usage of father adds to the confusion. It is interesting because one has to use logic and problem solving in a different way to figure out who is speaking and to determine that "that man's father" = "my father's son".
