For me, that age was 18.
My Father died, unexpectedly, leaving my Mom with 6 kids to raise. I had to drop out of college, after only one quarter, to come home and watch my siblings so she could work fulltime.
I was 18, my sisters were 16 and 13, and the boys were 6, 3, and 1 1/2. My Mom was 41.
We were ALL so young. Everyone was at a critical, formative point in their lives and things would never be completely all right for any of us ever again.
My Mom never remarried. She only went out on a few dates, men that she met @ Parents Without Partners who had children of their own that needed a Mother. She knew that bringing another man into our lives would be a disaster, let alone for her trying to Mother someone else's grieving kids.
None of us ever successfully recovered from that hell of a year, even to this day.
I'm stuck in 1965, at 18 years old, forever; and I wondered if there were others who might have become stuck as well.
Maybe you'll tell me when YOUR life became a moment in Amber.
