The Cat of the House

I entered the house the other day and sat down in the living room, which began a chain of events that continues to amaze me.  I am really at a loss to understand it or even rationalize it.  Here's what happens: I walk in the house.  Nancy comes up from downstairs, followed by the cat of the house.  We move to the living room, where I sit on the couch opposite of Nancy so I can visit with her and we both talk about our day.  Meanwhile, the cat of the house saunters over to my right and sits, waiting for the right moment when it can dive under the couch, and begin to sharpen her claws on the underside of the couch.  The only time this cat does this is when I come home and sit on that couch.  It never does it at any other time.  It annoys me to no end.  

And what's more, this cat knows it.  

There's a few things in life that I will never understand.  For example, I don't understand why no one holds politicians accountable to just answering the question in a simple manner.  Usually, answers are vague or redirected.  Why can't they just answer the question?  I will never understand what happened to Preparation A through G.  I wonder how will we ever know when we run out of invisible ink?  Why do we park on driveways and drive on parkways?  And I may never understand why this cat of the house has decided to torture me with her selectively annoying behavior.

I suppose (to be fair to the cat) it's because I haven't "embraced" this cat from day one.  That's probably why the cat has chosen me as the object of her cat hijinks.  I think this cat is being really unfair.  I am the one who does a lot of things for her.  Clean litter box?  Me.  Put fresh water in her dispenser?  Me again.  Make sure food is plenty?  Me, me, me.  This cat does not know how much I help her existence.  And this is how the cat responds to my actions toward her?  As I said - it's so unfair.

Maybe I should just show the cat some affection.  Maybe then the cat would stop annoying me.  

I don't understand why I don't do that.
