It is my opinion that my case is a mix of these two.  You should train 
yourself better to look for the "sig exists" or "sig doesn't exist".
Imagine a traffic light that only has one green light.  If its on go, if 
its off don't go. Same here.  Except that the light would only be red 
when you would ordinarily think go (like a stop sign).  I hope that was 
clear....
