Nacho vs. the spider.

So, at the time, Nacho was my household's resident BA (badass).  He could kick the crap out of any cat or dog unfortunate enough to cross his path.  He is even a decorated war hero...he fought in the Great Vulcan Wars of the early 21st century (other story to be told).  So it's late at night and I am coming home from a night out on the town and am approaching my front door.  As I am fumbling around for my keys I noticed a rather large and hairy wolf spider sitting by my door.  I am not a big fan of spiders and am wondering if I can open the door run in and then close it quick enough to avoid dealing with it inside.  I am fast but not as fast as, Speedy Gonzales, and the wolf spider was.  So, now I have one of the biggest wolf spiders I have ever seen, in the middle of my living room.  In comes Nacho the resident BA.  He takes one look at it and then enters ninja stalker attack mode.  I am thinking this thing is gonna die and become a kitty snack.  Nacho lunges at "wolfie", yes it now has been named, and then steps back...WTF?  This wolf spider is not backing off and has reared back on it's hind legs and is swatting back.  I am not sure what it thinks it can accomplish by doing this, I mean...this is the great and almighty Nacho it's up against.  Never the less, it's fighting back and my cat doesn't know what to do...this has never happened before.  Whats this?  Nacho is backing away from it.   I am in a bit of bewilderment as I watch this spider fight off Nacho and then the BA run away!  WTF!  Now I am faced with a  spider that just beat my cat and is now staring me down with all 8 eyes.  Hmmm....I begin looking for a large book or something to give me the upper hand in this battle when it makes a tactical retreat under some shelves.  I moved a few things around looking for this beast of a spider and it's nowhere to be found!  I did not sleep well knowing that I could have at any moment been ninja attacked by this huge spider...I never did find it and never did let Nacho forget that he lost to a spider.
