   Once you accept that light clocks are true clocks (and true meters,   
   they're actually the ultimate calibration tools for both distance and   
   time units), and how they behave relativistically in accordance to their   
   reciprocal state of motion, you'll be aware to have acquired an   
   intuitive grasp of (special) relativity features, and no longer feel the   
   need to cause misery to poor Albert and his (admittedly much less   
   intuitive) description of SRT.
