All the #$%@#$ time. I can't turn it off. I have to not look at
   people interacting and _not_ point it out when I see it or hear
   it. Overactive empathy glands or whatever. I can imagine myself
   in a time where I don't want to hurt the grass by walking on
   it... so I have to keep the inhibition circuits running.
   Empathy. I'm glad I have loads but it's sometimes a burden.
