Growing up with dwindling vision is one thing. Growing up with said vision and hearing the EMERGENCY BROADCASTING SYSTEM testing every single day on PBS, sometimes more than twice a day, was enough to send me running.
My worst time though was when I was seven; my grandmother had come to stay for a while. I was eating breakfast at the table when the GARFIELD cartoon I was watching cut to the E.B.S. announcer. She said I ran like all of hell's hounds were on my heels and refused to come out from under the bed for about an hour. I don't blame me for doing it.
Also the test pattern, the SMPTE color bars, did it, and did it well. Let's see, vertical hold notices, claw machines, I was quite the little coward.
