A memory of letting my first dog out, by opening the front door, and letting her go outside without boundaries or supervision. I followed her and she went around the corner of our street and sidestreet and started chatting with another dog through the fence. I have no idea how old I was, pretty young, I want to say definitely younger than 4, perhaps 3.
Also around that same age, having a taxi regularly take me from my house to a specific "school", for speech therapy classes. I was slightly retarded because I didn't hear so well as a kid, so that made speech difficult. Definitely younger than 4, so though it was hardly a single day's event so I remember that due to the repetition of events.
