I cannot express how much I dislike "The Giving Tree".
Everyone's familiar with this one, right? The one with the kid who keeps coming back to the tree that loves him, demanding more and more from it as he grows older until by the end of the book, he's reduced it to a pathetic stump of dead wood...but it's just fine as far as the tree is concerned, because that means it can give him a nice place to sit.
I love Shel Silverstein, but man...dude had issues. I mean, we're talking "my wife was secretly sleeping with my brother while embezzling from my company funds and framing me for possession of kiddie porn" issues with relationships, judging by that story. It views love as nothing more than an endless, voracious cycle of selfishness, where one party is capricious and oblivious to the depths of the sacrifices made by the other, while the other is a doormat for abuse.
If "The Giving Tree" were reflective of real love, there would be a forest at the end of that story. Because that's what real love does. It makes you bloom.
