Alice: Is this your new video game?
Ryan:
Yes, it is. You (MUST; NEEDN’T; HAS TO) try it. It’s great!
Alice:
How do I play?
Ryan:
First, you (MUSTN’T; HAVE TO; NEEDN’T) escape from the castle.
Alice:
How? Down the stairs?
Ryan:
Stop! You (MUSTN’T; DON’T HAVE TO; DOESN’T HAVE TO) open that door!
Alice:
Oh! Too late! Am I dead?
Ryan:
Yes. But you (MUSTN’T; MUST; DON’T HAVE TO) start again. Just press ‘B’ to continue.
Alice:
OK, thanks. What now?
Ryan:
You (NEEDN’T; HAVE TO; MUSTN’T) climb out of the window. But slowly! You (NEEDN’T; MUST; DON’T HAVE TO) be careful.
Alice:
Oh no. I’m dead again. I’m not very good at this.
Ryan:
Well, we (MUST; NEEDN’T; HAVE TO) play this game. I’ve got lots of others...
Alice:
No, no. I (NEEDN’T; MUSTN’T; HAVEN’T TO) give up. Do I press ‘B’ again?
