Emotional manipulation.
  I stay on constant vigilance against it.
  If I feel an emotional pull beginning within me, I ask if I want
  this feeling. If I do not, I cut it off.
  It takes practice, but there is PLENTY of practice to be found.

  I'm very empathic by nature but I have a limited supply. I
  apologize to wasps just before/after I kill them with poison.
  They deserve my empathy. A picture on the Internet does not.
