It sounds like it is a waypoint on the path of your life? When you pull the thread on "why", then you see this one light up?

I agree with you - it's really interesting that your brother remembers it so well, that it left such an impression on him. Perhaps he'll have other stories to tell you that will increase your self-understanding?
Sometimes it's helpful to me to see that my brother has the same wacky habits and tendancies that I do, since we learned them at home. Seeing them in him helps me to change my behavior!!!!
