Subject: Understanding the fundamentals, methods. (from Pickaxe book)

Hey chaps,

I'd just like to check that the following uses methods and that no classes or instance variables are created. I see that there are no @instance_variables..
Where's the object? What class is being used?
Am I correct in saying that say_goodnight is a method, where (name) is the parameter for it?
 
#!/usr/bin/ruby
# Tue Dec 27 15:42:59 GMT 2005
#  from page 13 of the pick-axe book
def say_goodnight(name)
        "Good night,  #{name.capitalize}"
        #  we use the output of the last result - this save time
end
# Time for bed...
puts say_goodnight('jayeola')
puts say_goodnight('john-Boy')
puts say_goodnight('mary-Ellen')
puts say_goodnight('mary-loo')
puts say_goodnight('silly-slapper')
puts say_goodnight('hex-editor')
