Welcome to my world . Try to line it up at a shadow near the edge of the wall , then estimate how far you ' re moving the reticle . It ' s most difficult on a well lit wall , at that point I just resign myself to making kill holes and blowing a hatch if there is one . <| sep |> the cause even if you tell a kid exactly how bad the world is they won ' t get it anyway . Kids don ' t have an understanding of how worldwide problems connect and effect different people , so it would be a waste of effort in the first place just to upset your kid over something they don ' t benefit from knowing . On top of that with the imagination children have no matter what you tell them they ' re gonna have false beliefs about the world . Part of growing up is realizing how the world is and what that means to you
