A flood of images washed over me:  of wives whose husbands would never come home again. Firefighters, police officers, emergency crews, medical technicians, and many brave, good men who weren’t trained to be heroes but who stepped up to the job. There were mothers who would give anything to have their sons or daughters arrive late or infrequently, just to have them walk through their doors again, and daughters and sons who wondered why daddy hadn’t come home, who would miss out on memories that my children were able to make.
