Perhaps it's human nature: We want to shield our children from pain, and what we get instead is life and heartache and lessons that bring us to our knees. Sooner or later we are handed the brute, necessary curriculum of surrender, we have no choice, then but to bow our heads and learn. We struggle to accept that our children's destinies are not ours to write, their battles not ours to fight, their bruises not ours to bear, nor their victories ours to take credit for. We learn humility and how to ask for help. We learn to let go even when every fiber of our being yearns to hold on even tighter.
