dude, if you spent a month with a clone of yourself, you'd get
   on your own nerves. People who are like you (speaking in general
   "you", including me) will magnify the flaws you see in yourself
   and they will irritate you to no end. But people who are
   slightly more clever or smarter or slower or wittier or dumber
   or prettier or uglier -- ones who differences are on the same
   spectrum as you but at different spots, will be infinitely
   interesting because they'll remind you of who you were, who you
   might become, who you could be but never were nor never would
   be. That's what I think anyway. "
