=begin

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.
