I saw the strikethrough, and did not understand why it was there, so i read on.
Whilst i guessed at the beginning that you could be writing about yourself, the strikethrough isn’t an obvious confirmation that I was right.
It would be much more obvious to write either in the middle “In case you haven’t already guessed.......” or continue writing about the friend until the very end, when you can add the following: “ in case you didn’t already guess, I know, because that man was my father. ‘
Even more difficult, but perhaps quite satisfying and rewarding to the reader would be to write the story through the eyes of your brother, mother, or even your father. Then you could end the story a bit like that song from Kenny Rogers about a soldier caught playing cards in church. The song finishes with “I know, I was that soldier.” Or something like that.
I can imagine it would be extremely difficult to write the story through the eyes of your father without putting your bias on to it. It might though provide you with more release.
That's a good point, thanks for the advice. I went back and cleaned up that spot a little bit to make a separate break along the lines of what you suggested. This does make it a little smoother and more logical in the flow.
Maybe I'll rewrite this down the line after some years to see how I can reflect on it then. It's all fairly fresh so it'd be interesting to see how my view changes over time.
Thanks again for taking plenty of your time to help, and for your generous vote.
