Mortality Mentality

Who was the first person in your life to die? This should be someone personally known to you rather than an idolized public figure. How old were you, and what kinds of thoughts did you have at the time? Was it the first time in your life that you'd confronted your own mortality? Did you just accept it as a natural part of life, something you wouldn't have to personally face for many years? Or did you lie awake at night agonizing over what death meant, or felt like? What did you learn from this initial firsthand experience with death?
