Expression...

Why is it that the things we most want to say are often the hardest to express?There is someone in my life who is very dear to my heart. I love her as my own child, though she is not. Why is it hard to simply say "I love you"? Is it fear of rejection? Embarrassment?I know I will always come in second best, no matter how close that second may be. There's nothing that will ever change that fact, but it still hurts.Why is it that the emotions we want to show are often hidden far more easily than those we'd rather not experience?It is so easy to show our anger, why don't we fear rejection as a result of our anger rather than as a result of our love?
