Deaf grandma - Exercise

Whatever you say to Grandma (whatever you type in), she should respond with this: 
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. You can’t stop talking to Grandma until you shout BYE.
