Intruders
I have a tendency to imagine improbable situations and try to picture myself in them. One that I frequent is: Someone appears or breaks into your house without your knowledge and surprise you while your eating, or sleeping, brushing your teeth, swimming, etc.
Who is that person? Why are they there? What would you do?
Try to make an interpretation of a scene like that in a ficly! Have fun! Be original! Think outside the “psycho coming to kill you” box if possible. :P
