Wow. A very interesting question. After reading the current replies I sat back to ponder this. At first I realized that I did not relate to anyone when I was younger. My father was very strict and pushed me to be the 'all-american jock' like he had been. At best I was mediocre. My mother (and her side of the family) had moved away soon after my father got custody of me when I was 4, so they weren't in the picture. I was never very close to my fathers parents, so they are out.
Perhaps my Great Grandmother (fathers mothers mother). She has always been somewhere in my thoughts and even though she died when I was fairly young (10-ish) I do remember her as always being supportive - in a general way - and very loving towards me. You see, my family has always been very clique-ish. My Aunt, and her family, got most of the attention from my grandparents, when they were alive, and my father got basically the scraps. Though again, I do not remember my Great Grandmother as choosing favorites.
As for neighbors, teachers, etc... I was basically the ultimate loner and did not have any more contact with those types of people than I had to during the course of a day, so they do not stand out.
Embarrassingly, Wonder Woman and Cat Woman probably had more of an impact on my childhood than any actual person. I am not really sure what this says about the person I have become, but it is what it is...
