A slight itch travels across your skin, across your brow and through the muscles of your arm.
As you scratch your brow, you notice the gash in your hand, it is infected and green and it doesn't look healthy at all.
You cut yourself with the scissor before, just a little cut on your finger as you cut out a band-aid for your gash.
Flies are on your floor, they can't fly.
Why did I do this?
