Ethan: where? at work. Where was I supposed to be?
Mollie: In the evening 
Ethan: At home.
Mollie: I called you and you didn't answer
Ethan: I left the mobile in the bedroom
Mollie: it happened that I was around your place about 10pm and all the lights in your apartment were off...
Ethan: Are you stalking me?
Mollie: Are you cheating on me?
Ethan: Don't be silly.
Mollie: Don't "silly" me
Ethan: I was listening to music
Mollie: In darkness?
Ethan: Yes, it's very pleasant. You could come over and check for yourself!
Mollie: Maybe I should have done it!
Ethan: Oh yes!
Mollie: Anyway, it seems all too strange
Ethan: you seem all too strange to me
Mollie: Sorry.
Ethan: Come here and let's talk this over
Mollie: Ok. I'll be there in 40-50 min
Mollie suspects that Ethan is cheating on her, because yesterday he had all the lights in his apartment off. Ethan tries to convince Mollie that he was just listening to music in the dark. Ethan and Mollie are meeting in 40-50 minutes in order to discuss it.
