Subject: Can't get 'require' to work

I just started tinkering with Ruby.  From "The Poignant Ruby Programmer"
or whatever it's called (you know what I mean) I tried running the small
example but get an error.
This is the first file called m2.rb:

require '/usr/home/me.rb'

 # Get evil idea and swap in code words
 print "Enter your new idea: "
 idea = gets
 code_words.each do |real, code|
   idea.gsub!( real, code )
 end

 # Save the jibberish to a new file
 print "File encoded.  Please enter a name for this idea: "
 idea_name = gets.strip
 File::open( "idea-" + idea_name + ".txt", "w" ) do |f|
   f << idea
 end

And this is me.rb:

code_words = {
   'starmonkeys' => 'Phil and Pete, those prickly chancellors of the New
Reich',
   'catapult' => 'chucky go-go', 'firebomb' => 'Heat-Assisted Living',
   'Nigeria' => "Ny and Jerry's Dry Cleaning (with Donuts)",
   'Put the kabosh on' => 'Put the cable box on'
 }

When I do: ruby me2.rb and enter any of the code_words above, I get:

 me2.rb:6: undefined local variable or method `code_words' for
main:Object (NameError)

What am I missing?
