From this brief episode, I learned what it meant to be mesiras nefesh for the sake of doing chesed. My father took the time to care for children who were random strangers, even though it caused him some inconvenience. I can apply that lesson in myriad ways and hand it down to my children as well. The task at hand is to give that lesson and my father eternal life, by emulating those teachings in dozens of ways, whenever the opportunity presents itself. Yehi zichro baruch.
