My earliest memory is of my second or third birthday-most likely third birthday. I was living in Hong Kong at that point with my grandparents and my parents were in America. I vividly remember my grandparents showing the cake and telling me that my parents sent me the cake from America and me believing them. I don't remember much else.
Even though I wouldn't be as easily tricked now, I think my personality is still the same. The fact that it was a big, happy event probably made it memorable.
