Blocking for Scene

The scene I am doing is the monologue from Forrest Gump where Forrest Gump is talking to Jenny's grave about how life has been and how Little Forrest is doing and how Little Forrest wrote her a letter. This scene in the movie does not have a lot going on but I am going to try and incorporate movement into the scene and maybe go kneel down in front of the grave and kiss it as if I am kissing her as like a symbol as that even though she is not physically with me that she is still with me. I may also just like pace a little bit to show that I am upset and also to try and extend the scene since the monologue is fairly short and I want to show a little bit more emotion and how this has affected him. I'm not exactly sure as to what I am going to use as a grave yet but I am going to hopefully going to figure that out soon and I am going to have an envelope that says "Momma" on it from "Little Forrest". As for now thats all I have but I am working on other ideas and how I would incorporate them, they are just not clear to me right now.
