He arrived at a wonderful summer's night party many years ago. I couldn't see him but he was there with me after being dead for about three years. It was clear that he wasn't there to enjoy the good time. He was there on a mission. The gravity of his presence zapped my good mood.
A short time later I had an irrational drive to protect a girl there who I worked with, but was not a close friend of. She was with her boyfriend and I was with my girlfriend, and so my behavior was not going over too well with them. I couldn't give a rational reason why I needed to protect the girl that night. It's not not my friend spoke to me. But, I somehow felt directed. And, I just couldn't put the pieces together.
On their way home from the party, she was killed when a car pulled out in front of their motorcycle.
My friend hasn't visited me since then. But, I won't let what people think keep me from protecting someone if he visits me again.
It just dawned on me as I write this that my friend almost certainly had been acquainted with the girl who died that night.
