I found out the hard way not to hole up overnight with people you don't know.  I used to be a Doctor.  I was viciously attacked and killed during the night by a psychotic HUMAN called Nate Saint.  He took my wine, too.
I am now a zombie, and it let me tell you, it aint what its cracked up to be.  I try to speak, but can only say things like "grrrrhah" and "uughhhhh."
I try to paw at the barricaded doors, behind which, you try to sleep in peace, but I seem to be weak. Its hard to get them completely down.
 I'm headed for a hospital I know of where there are many of us waiting...
