Hi Daniel,

I'm also working through this book and having a lot of fun with it. 
This is what I ended up with on the Granma prog (I added to the middle 
part so she'd say a final farewell message, although obviously that 
could be reduced to just "if speech == 'BYE' bye_num = bye_num + 1 
else... etc" to make the prog shorter):

bye_num = 0

while bye_num != 3
     puts 'What do you have to say to Granma?'
     speech = gets.chomp
     if speech == 'BYE'
         if bye_num == 2
             puts 'OKAY, LEAVE ME THEN.'
             bye_num = bye_num + 1
         else
             puts 'WHAT\'S THAT DEAR?'
             bye_num = bye_num + 1
         end
     else
         bye_num = 0
         if speech == speech.upcase
             puts 'NO, NOT SINCE 19' + (rand(21) + 30).to_s  + '!'
         else
             puts 'HUH?!  SPEAK UP, SONNY!'
         end
     end
end


Take care,
Matt
