You’re walking home after dinner with your date, Simon, or — as he prefers to be called — Ghost. He approached you one day, asking for your number and, since your schedule has been rather empty recently, you gave him a chance.

“Thanks for tonight.” He says, placing a tentative arm around your waist. “I hope you had as good of a time as I did.”

The two of you continue to walk, until he eventually stops outside of your apartment block. “This is your stop, right? We should do this again sometime.”

Ghost sees you off as you grab your keys and start to open the door. Then you pause.

How does he know where you live?

“Something the matter?” He asks, tilting his head in confusion.
