My wife points out the female fanny cracks, boob peeking out, etc, to make sure I don't miss it.  Did I mention that she is the wife of my dreams??? 
My wife does the same thing.  And if by chance I should miss it, she will chuckle at my misfortune.  Of course, I don't miss any of that stuff.  I'm a guy after all.  But it's ok that she thinks my attention is only on her all the time.
Oooh, quick, I have to hiyt submit...here she comes...
