Doorbell: "Ding-dong!"
Sandra: [Walks to door, opens it, sees random lady with little kid in her arms standing outside.]
Lady: "Hi!" *[Holds up little girl. Gives me an expectant look.]
Sandra: "..." [Blinks. Waits for... some kind of explanation.]
Lady: "This isn't yours?"
Sandra: "... No."
Lady: "... Oh. Ok then." [Turns around and rings bell next door.]
Sandra: [Closes door.] "Well, that was random."
