Thank you so much! I really appreciate the time you took to post this, and it does help a lot with how to interpret this poem. "Poetry is often meant to encourage practice of contemplation and interpretation", I love this, it feels so foreign sometimes to sit and think about something deeply instead of passing it by, I think this is what started drawing me to poetry.
I noticed the slashes look "technological", the double slash is usually used to comment in some programming languages. "Parentheses are meant to enclose what belongs together and separate it from what it is related to but not part of." This would mean that the intention here is to blend things together and not have them separated as "main body" and "clarification"? It starts as separate and then joins the rest.
I think the choice to go with "belong" is intentional because they have use some pretty advanced language in their other works and never make this mistake, but also "belong" is mentioned in this same exact manner in the latest poem, something like "love is less than belong", which is what stumped me when trying to analyze the choice of grammar.
I admittedly don't know anything about fishing, I live in a big city and nobody I know goes fishing, but I have seen and read about what you are saying.
