On why I hate "The Giving Tree"

   I never liked the book "The Giving Tree" as a kid...I still don't. It always depressed me, because the kid/man was so selfish and more or less killed the tree and the tree loved him so much that her self-sacrifice made her happy.
   Maybe on a subconscious level (though I am now becoming aware of it) I don't like it because it hits too close to home.  God gives and gives and gives and we happily take it, never thinking of what it does to Him, how we have hurt and damaged Him for our own  happiness. He went so far as to DIE for us, and we still want more. By human nature we are selfish, but how can we not be? All that we know is what we directly experience.  So to us, the world revolves around us and our problems or happiness.
   I think what bothers me most about "The Giving Tree" is that the boy NEVER thanks the tree for her generosity.  And she's not really happy because he keeps abandoning her. Do we do that to God? Am I guilty of asking for things and then not even being grateful for them; abandoning Him when I feel I have gotten what I want? I hope not. I try to be thankful and praise Him no matter what is going on. I hope I am not just taking and taking without being thankful and trying to repay the kindness I've been given. Something to focus on I guess...
