It is indented. Must be your client.

Try this:

Tools --> Options --> Read tab

Check "Read all messages in plain text"

The problem was that I didn't realize that I messed up the first
Grandma program (which reinforced some misconceptions because the
program was working ok). Then I sort of got this idea that I had to
use a loop inside a loop and really couldn't get out of that box.

Everything is obvious now. 

Agony of defeat, ecstacy of success.


Anyway, here's the final program:

(hopefully I don't have any superfluous code this time around)


-----------------------------------------------------------------
number = rand(21)
number2 = 0
keep_count = 0

while keep_count != 3
	input = gets.chomp
		if input != 'BYE'
			keep_count = 0
			puts 'HUH?! SPEAK UP, SONNY!'
		else
			number2 = (keep_count + 1)
			keep_count = number2
				if keep_count != 3
					puts 'HUH?! SPEAK UP, SONNY!'
				end
		end
end

puts 'NO, NOT SINCE ' + (1930 + number).to_s + '!'
----------------------------------------------------------------
