I have not seen where you are talking about the pain of the loss - the focus I have read about here is on getting him to act differently - not you wanting to talk about your fish connection. That is where I am saying it doesn't seem to line up - you say you want to talk about the pain but your descriptions here are about getting him to act differently. I mean - the it is so small, and how would it hurt to have the fish there, and so on - that is about how he acts - not how you talk about pain.
I am just giving my observations on it -if you don't think they fit then okay..
