How often do I ask for something I don’t realize I already have?

Izzy just came in from outside and began meowing.  “Feed me.  Feed me now.  Now.  NOW!”  What he doesn’t know is that I opened a can just five minutes before and put it down for him.  So he’s freaking out and asking me for something he doesn’t yet realize has already been given to him.  I wonder how often I do that.   Like asking the Universe for something that I am too blind at the moment to realize I already have immediate access to.
