Call from the real Megan

Nick undressed and crawled into bed. First thing in the morning he would change back.
Her sleep was uneasy, Nick was used to sleeping on his back. So when she got to sleep it was a deep sleep.
Nick awoke to the phone ringing.
Without thinking she picked it up and said "Hello" in a confused sleepy stupour.
Megan's voice said "Tell Nick Megan called to say fuck off you whore." and she hung up obviously slamming the phone.
Nick woke up in a start. "Oh shit! She thinks I'm cheating on her."
