Fear comes in many forms. Terror, phobia, agitation, horror. There is the fear of losing a child. My three boys are my world. I fear my life would stop if they were taken from me, no matter what that looked like. They are now grown men, but still my children. I don't have many things that I truly fear beyond that.
I had a fear of being kidnapped as a child. I grew up in the era of the Zodiac Killer, The Son of Sam, The Green River Killer, and so on. It was a true and valid fear in the 1970s. Not so much today. I'm 48 and less likely to be kidnapped.
