I’m trying to write a scene in which a boy runs down a dock and jumps into a pond. Rather, I’m writing a scene in which the middle-aged narrator tries to remember what that feels like. I can’t think of a good way to do first hand research – which would otherwise be the best thing – so I’m really trying to remember what that’s like. I don’t really want to write a scene in which said narrator tries to recall said experience and fails miserably.

What in the world is that feeling, exactly?
