My earliest memory has to be the day that one of my friends got bit by a dog. I was about 7 years old and we had a BBQ with all of my family and my parents close friends came to visit.
We had a chow-chow at the time and he was not really an aggressive dog. Right before I knew it the dog was on top of my friend and my parents were rushing to aid him. My mom pulled him off and threw him across the patio. We quickly ran inside and my parents instructed us to run upstairs.
All I remember from then on is a lot of crying, yelling, and sirens.
That is my earliest childhood memory.
