Blood On Your Hands
Here’s a question I’m almost afraid to Google the answer to: how much blood has to be on someone’s hands before you should comment on it? Because the way I see it, one of two things has happened: first, maybe the person has injured themselves badly and for some reason hasn’t noticed it yet, and your pointing it out could help them get the medical attention they need.
Alternatively, they have murdered someone, and maybe your pointing it out could help you get crucial details that you can give to the police later. Of course, on the other hand, maybe pointing it out makes you a loose end that the murderer needs to tie up later, and they come back at the end of your shift and kill you too. I’ve changed my mind: don’t bring it up when someone’s got blood all over their hands.
