My earliest memory I can remember was probably around the age of 4 when I was at Oregon visiting my dad, who was in graduate school at the time. I remember it being a rainy day, with the sky being gray and puddles everywhere on the ground. It was definetely cold. I was holding either my mom's or dad's hand (or both) while we were walking down some kind of sidewalk. I seemed excited at a sight of a blue shoe and ran up a flight of concrete stairs to touch it. I remember saying something to my mom, who was kneeling down next to me, probably about how wet it was.
I don't know why but I always remember this memory when I think back to my childhood. It doesn't hold any particular significance, and is definetely random. Maybe the reason why I always have this memory is because my family is usually never together. I guess I find warmth in this memory because I was with both my parents, just enjoying a walk together.
My personality has definetely changed from back then. However, I was a curious child. I still am. That part of me probably won't ever change. Looking back at the memory, I see a totally different person. It's weird because that child is obviously me, but for some reason I feel like it's also someone else. Maybe I actually did change a lot. Even when I look back at myself as a freshman, sophmore in high school, I feel like someone totally different. I don't whether it's because of my memory or because of actual personality changes.
It's interesting that you could remember vivid details of your earliest memory. Most early memories are fragmented with minimal details. The fact that you remembered it so well might be due to its significance in your life. Like you said, your family were not usually together and this memory is stuck in your mind because its the mental picture of the family that you want.
