Your Finger's Bleeding Day!
You got some on the polaroid. Worry about the band aid later. His eye's gone. And the pattern on his sweater's been interrupted. Place the polaroid on the desk, careful to keep it level so the bauble doesn't slide. Get a paper towel and try to dab it up but for God's sake hurry.
It's not going to be clean. Prepare yourself. You bled some of him away. You really should make a point of getting the important photos tucked away before you sew buttons back to coats.
Happy Your Finger's Bleeding Day!
