Possibly the most dramatic introduction to a post that I will ever have. Let me milk it shamelessly.
I'm done. A bit of investigation showed several things -
1) Ever since I stopped caring about my apperance, I have let my nails grow to a stupid extent.
2) The cuts are approximately of the same distance apart as are my fingers.
3) A known side effect of this medicine is, while sleeping, the person gnashes their teeth together and thrashes a bit (only indicated by waking with a saw jaw and bruises on the arms and legs).
I know. I am a super slueth. Nothing gets past me. I have noticed a pattern in the evidence and have concluded that the only possible explanation is -
I'm a werewolf. They always wake up with weird injuries covered in blood with no idea how they got there. However, it is usually someone else's blood.
I feel cheated.
