It's amazing to me that anybody would think in 2015 that some
people think we _can't_ communicate with animals and plants. All
one has to do is have a pet.
Communication is more than words on paper. There doesn't have to
be a theory for something to really happen - it's just nice to
get a decent story from Scientific circles; they carry some
authority in many people's minds and its good when they get it
right.
