Happiness from an Apple

I was going to make this post about the overview of my recent observations, but something interesting happened today that changed my mind.  So I will just be discussing some of our Sunday because I feel like it was, in my opinion, important.
I change his cage whenever I feel it is necessary. And today happened to be one of those days.  I could feel that he was angry while I changed his cage.  Mainly because he was making these cooing like noises and was in an aggressive stance.  The stance consisted of him leaning forward toward me.  It doesn't sound like an aggressive stance but compared to his regular pose, it was.  That made the actually act of changing his area somewhat difficult, but I still managed to get it done.  In the end that got Little Bird in a better mood.  Later that day I was eating an apple and that happens to be one of Little Bird's favorite fruits.  I sat on my bare floor and peeled part of the apple with my teeth.  I couldn't help but notice him staring at me the entire time.  Once I peeled a fair amount of the apple, I stood up and bit off a piece and fed it to him.  He wasted no time and immediately ate the entire portion within five minutes (the piece was roughly the size of a small bouncy ball cut in half).  I also left three more chunks in his cage for later.  Once he finished, he turned around in circles on top of his cage and cleaned his beak off on the cage bars.  What I found to be interesting was that he kept turning around in circles.  Slowly but enough for me to take notice.  I believe he was happy.  Every once in a while he would peer down into his cage and see the other apple fragments but refused to go into his cage and eat them.  By then I had finished my apple so I went up to him and offered a bite, but he turned me down.  About six or seven minutes later his breathing slowed (noticed from his chest expansions) and his eyes started to close.  This wasn't an eventful day, but I like to believe that Little Bird was happy today.  Just one tiny insignificant piece of an apple made him happy (well it must have been significant to him).  It made me feel happy.
