Subject: Another Deaf Grandma Topic, different issue

I'm trying to learn using a tut, and I'm getting stuck on one of the
exercises. Google is giving me squat.

It's about Flow Control, specifically while and if-then. I understand it
totally, but I need, well, it's hard to explain.

I've successfully finished this:

Write a Deaf Grandma program. Whatever you say to grandma (whatever you
type in), she should respond with HUH?! SPEAK UP, SONNY!, unless you
shout it (type in all capitals). If you shout, she can hear you (or at
least she thinks so) and yells back, NO, NOT SINCE 1938! To make your
program really believable, have grandma shout a different year each
time; maybe any year at random between 1930 and 1950. (This part is
optional, and would be much easier if you read the section on Ruby's
random number generator at the end of the methods chapter.) You can't
stop talking to grandma until you shout BYE.
Hint: Don't forget about chomp! 'BYE'with an Enter is not the same as
'BYE' without one!
Hint 2: Try to think about what parts of your program should happen over
and over again. All of those should be in your while loop.[/spoiler]

But now I need to do a bit more, and I can't figure out how to do this:

Extend your Deaf Grandma program: What if grandma doesn't want you to
leave? When you shout BYE, she could pretend not to hear you. Change
your previous program so that you have to shout BYE three times in a
row. Make sure to test your program: if you shout BYE three times, but
not in a row, you should still be talking to grandma.

Oh, and here's my code:

puts 'it\'s yer ol\' gramma hobblin\' over! What do you say?'
you=gets.chomp


 while you!='BYE'
      if you!=you.upcase.chomp
      then
      puts 'HUH?! SPEAK UP, SONNY!'
      you=gets.chomp
      else
        if you==you.upcase.chomp
          then
          puts 'NO, NOT SINCE 19'+(rand(21)+30).to_s+'!'
          you=gets.chomp
        end
      end
 end
