Hello! I found your story on Review Requests and as it kept popping up on the home page, I decided to give it a go. I really enjoyed this piece. It reminded me a little of Huckleberry Finn or The Andy Griffith Show. To me, this story didn't take place in modern times, it has been years and these two boys are older now, telling a story of when they would fish everyday they could. When the two boys would pick at each other I was chuckle a little or a smile would come to my face. It's good to make your readers have a reaction to what is going on whether it be a bad or good one.
As for the technical part of your story I didn't find much problem, however, I do have a couple of suggestions.
The line "You've just gotta keep faith." I think it would flow better if it said "keep faith" or "have faith."
The line "...More and Bigger things..." Would do nicely as "Bigger and better things."
These are just my suggestions as an amateur writer and this is a wonderful piece. Good luck with everything and Write on!
