These sources of strength are with your loved ones. For many of you, your first instinct was to call home and let your moms and dads know that you were okay. Others took on the terrible duty of calling the relatives of a classmate or a colleague who had been wounded or lost. I know many of you feel awfully far away from people you lean on and people you count on during difficult times. But as a dad, I can assure you, a parent's love is never far from their child's heart. And as you draw closer to your own families in the coming days, I ask you to reach out to those who ache for sons and daughters who will never come home.
