Someone just posted a question about what to do if you have a “creepy” visitor.  Well, if you’ve prepared properly you already have a built-in alarm button concealed under your desk.  And, if you have the mindset for it, you’ve already thought about weapons for self-defense.  But what if you haven’t?  Hmmm.  Talk fast and bluff are probably your best choices.  Act confident.  Maybe even tell them you have another visitor coming.  Get them out the door and close the door.  Of course, if this happens after everyone has left for the day your problems increase.  Better by far to be prepared.  Start by reviewing what I’ve posted already.   And think about the unthinkable.
