My earliest memory was about the time I was 3. I remember that we were in a department store and there was a cool robot toy I wanted to buy it. But my parents would not buy it for me (I don't remember why). The extraordinary circumstance I guess would be the anger/sadness of not getting a toy I wanted.
Your earliest memory is very similar to mine. The earliest recollection i could remember was of me being sad/disappointed that my mother wouldn't let me do something. I wonder why it is that our earliest memory is of a negative emotion. Do you think that your personality is still the same as before?
