Victoria Stillwell probably hasn't delt with an UPS truck either.
Mine get so worked up when they hear it, even if it's on a different block, that "if" he does come here, Azrael is so worked up that she would definately bite that delivery man if I didn't have the expen in front of the door to keep them from bolting out. She almost got run over one time chasing an ups truck, and is why I put the expen up.
