My earliest memory is from when I was in kindergarten, so I guess around 5? I am not sure what age I would have been.
My dad was taking me to kindergarten, which was something I had gotten used to because he had done it so many times already. I slowly learned that if I took off my seatbelt before we got to the place I could get out faster. After getting used to doing that every morning, I began to wonder if there was anything else I could do to get out faster. THen the idea struck me, I could open the door before we got there!
So, the next morning when we were turning into the kindergarten I opened my door (remember I had no seatbelt on) and as I did my dad's head snapped to my direction, and he hollered, "SHUT THE DOOR RIGHT NOW!" Obviously I had not thought far enough ahead to see the risks of opening the door, and it wasnt till my dad explained said risks to me that I understood why I was yelled at. So to this day I remember it, the yelling probably made it stick as well as it has.
I actually still identify with this much younger, much more immature version of myself. I feel like my immature acts now source out of and connect to this younger part of me.
