Partly, most objects communicate only with objects they create and the 
object that created them.

class A
  def initialize
    arr=[1,2,3,4]
    arr.last
  end
  def ask
    return arr.first
  end
end

a=A.new
last=a.ask


Here the object we are currently in creates a object a of class A, it 
communicates with this object with a.ask. The object a itself creates an 
Object arr and also communicates with that. This is the way most object 
communicate with each other.

If you need two object (A and B) that are created by a third object (C) 
to communicate with each other then you are probably doing something 
wrong (although not always) and it might have been better if Object A 
had created object B instead of letting Object C create both.

Hope that clears some things up :)
