7x7 Brief

It seems that for some reason my mind is completely blank for the 7x7 brief. My story is called "The Misfortune of Edward Foster" and is about a man who slips on some steps and dies and then becomes a ghost and doesn't realise until he gets home but for some reason his son can still see him and he appears normal to his son and then he meets a woman ghost who has died from some sort of disease and then she disappears through a wall and then the story ends... got it? (lack of punctuation was deliberate). So needless to say I am struggling with the ideas gen. and I'm actually quite glad to be in Uni on monday to get some help.
