Subject: How to access a method in the parent class

Hi, I'll explain my problem with an example code:

-----------------------
module M
	def hello
		puts "hello !!!"
		B.new
	end
	
	class B
		def initialize
			puts "B instance initialized !!!"
			bye()   <--- ERROR !!!!
		end
	end
end


class A
	include M

	def bye
		puts "bye !!!"
	end
end


a = A.new
a.hello
-----------------------


I want the following behaviour:

irb> a.hello
=> "hello !!!"
=>  "B instance initialized !!!"
=> "bye !!!"


But the last bye() gives an error since, of course, "bye" is not defined in B 
class, but in A class.

I know that if it would be:
------------------
module M

	def hello
		puts "hello !!!"
		bye
	end

end

irb> a.hellp
------------------
This works since "bye()" calls the "bye" method in class A. But this is not my 
case.

How could I call A#bye method from M::B class?

Thanks a lot.
