I can't use "Until" because it wasn't covered in the book so far (even
though it seems pretty straightforward what it does). Ditto for "+-"

What was covered so far up until this chapter:

if, else, elsif, while

The first thing I tried was nesting IF's and WHILE's in different
combinations without using a variable to track the "BYE"s. I thought
that this would be the elegant solution, but really couldn't come up
with a way to do it.

So then I falled back to my first idea of "use variable to track
BYE's." But it looks like I'm not understanding the rules of nesting
and when/how a branch finishes and kicks you back to the previous
branch.

Here's what I had when I gave up:

------------------------------------------
input = gets.chomp
number = rand(21)

number2 = 0
keep_count = 0

if keep_count != 3
	while 
		input != 'BYE'
		puts 'HUH?! SPEAK UP, SONNY!'
		keep_count = 0
		input = gets.chomp
			while
			    	input == 'BYE'
				puts 'HUH?! SPEAK UP, SONNY!'
				number2 = (keep_count + 1)
				keep_count = number2
				input = gets.chomp
			end
	end	
else
puts 'NO, NOT SINCE ' + (1930 + number).to_s + '!'
end
-----------------------------------------


And here's the regular Deaf Grandma solution that I used:

----------------------------------------
input = gets.chomp
number = rand(21)

if
	while
		input != 'BYE'
		puts 'HUH?! SPEAK UP, SONNY!'
		input = gets.chomp
	end
else
	puts 'NO, NOT SINCE ' + (1930 + number).to_s + '!'
end
-------------------------------------


Thanks.
