See those tiny dots on my fingers? They are both on roughly the same spot, one on each finger. Tiny Blood Blisters! They have been there for a week. Now, blood blisters usually require a little bit of pain, don't they? I should have noticed if I were to do something to cause these, wouldn't I? WHAT could I have done to make these appear? Nothing. That's what. Think about it.
I have been taken over by Pod People while I was sleeping. These are the spots they poked their probes in. Only plausible explanation.
