I get flashes of snippets, all the time. Ideas for short scenes, poignant scenes, great scenes. Problem is, they all stand alone. Context would stitch them together, but I have no context other than my own life, and I don't want to use that. Fiction is suppose to be fiction, after all.
And, more often than not, my little scenes end up more like speeches, or soliloquies, than actual scenes. The one guy talks and rambles and blathers and the other guy just says, "Uh huh" every now and then. Or maybe he nods or shakes his head, depending on the circumstance.
I dunno. I'm probably over-thinking things. I do that a lot.
