Not Your Cup

I always keep a supply of disposable cups in my house.  When I'm here by myself, I know all of the used cups are mine, so there is no problem.  When company comes, having the cups cuts down on the dishwasher load, but used cups can become a problem for identification.  Once in awhile, we write our names on them with a Sharpie, but most of the time, they go unidentified. 

I had six extra people in my house for a week.  A couple of days ago, I picked up a foam cup on the table that someone had written on:  NOT YOUR CUP.  I chuckled.  Perfect!  No name required!  All anyone needed to know if they inquired was that it wasn't theirs.  Whose it was didn't matter.  It was not their cup! 

Of course, it took only seconds to figure out that this was my granddaughter's creation, but my mind raced to other applications to prevent theft.  Not Your Money.  Not Your Credit Card.  Not Your Pillow.  Robin (my granddaughter) probably doesn't know how ingenius I thought her missive was.  How creative!  I should have tattooed on my "ex", NOT YOUR HUSBAND.  Ha!  But I digress...
