I've known some pretty ego-centric people.
But you, my dear, take the cake. You take it, and then you complain that it wasn't your favorite flavor.
Surrounded by people. By wisdom that surpasses your own, by experiences beyond your reach, by perspectives you will never see, and you're the one doing the talking. No one can teach you.
No one can love you. Because despite all your talking, you've decided that no one will ever know your every last self-centered thought. No one will ever completely break down your walls. Because you've created a rule for yourself: keep up at least one brick.
And then blame the brick on the person who made the cake.
