The Wrong Number

Laura: Hello?? Who is this?

Unknown Number: Sorry I think I dialed the wrong number

Laura: Ah okay, no worries

Unknown Number: Wait

Unknown Number: You're Laura, right?

Laura: Uh... yeah? Do I know you?

Unknown Number: You live at Bergmannstraße 14, third floor, apartment B

Laura: What??? How do you know that

Laura: Who are you???

Unknown Number: I just want to warn you about something

Unknown Number: Stop looking at your phone and look behind the living room curtain

Laura: Dude stop, this isn't funny

Unknown Number: This isn't a joke, Laura

Unknown Number: The living room window

Unknown Number: The curtain is moving

Laura gets up from the couch and walks slowly toward the living room window.

Laura: I looked and there's nothing there, the window is closed

Laura: It's the wind

Unknown Number: No Laura. The window was open 10 minutes ago.

Unknown Number: Someone closed it from the inside.

Laura: What????

Laura: How do you know it was open???

Unknown Number: Because I saw it open

Laura: From where did you see it???

Unknown Number: That doesn't matter right now
