You decide that reading someone else's mail isn't a good idea. After all, you are a guest here. After sitting around for a while you find nothing else to do in the little room.

The computer speaks again. "I have mail for lain. Would you like to read it?" You can change your mind and read it or just sit around.

To read the mail tell the computer "Yes".
Or you can just sit around and realize that if this were a choose-your-own-adventure book you would be sent back to page 1.
