Subject: Setting class variable from parent class?

Hi All!

I'm trying to teach my Parent class how to set variables into its Child 
class; ie

class Parent
  def self.set_my_class_variable(value)
    reference_to_my_class.my_variable = value
  end
end

class Child
  set_my_class_variable "hello world"
end

I think what I'm missing is the way to reference the Child class. I've 
been wrongly supposing that

  Parent.set_my_class_variable(value)
    @@my_variable = value
  end

would be doing the work. But the '@@' syntax sets the class variable to 
Parent.

Thank you,
Marco
