Nobody

There is nobody in sight. Whoever was trying the handle they have gone. You shut the door and rush for your phone. No message. You dash off a fervent apology

Mistress I am so sorry. I failed to leave the door open. I am ashamed at my thoughtless mistake. Please forgive me.

The icon stays grey. Your message has not been delivered. You wait by the phone. Half an hour later it still hasn't changed. You know now that she won't be returning today. You clear away your preparations with a heavy heart. Throughout the day you keep checking your messages. You're beginning to doubt yourself. Was it even her? Did you just imagine the sound of someone at the door. Maybe it was a joke on you and she never planned on showing up at all.

Finally that evening the icon has changed. Your message has been read. The reply comes half an hour later.

I'm very disappointed. I put a lot of effort into my preparations today. When I found the door locked I decided you had chickened out. I don't normally give second chances. You will have to earn my trust.
