C Horror Movie

So it's Friday and I am working today - I use the term loosely as see previous. I wonder into the rest room. Pick a stall and notice that it is really dark - and then there's a flash of light - and then it's dark again - and then a flash of light. It reminded me of a strobe light and I kept looking around waiting for the walls to crash down or someone to burst through the door with a knife. I keep getting this feeling each time I have to go to the rest room today. Yes now I remember why I don't like horror flicks much - they put the most irrational thoughts in your head!
