Rob wakes up to the sound of an unfamiliar alarm. He opens his eyes blearily and sees his watch lying on a girl's dressing table. He looks over his shoulder and sees a dark head on the pillow beside him. He almost reaches out, saying Cassie? but then he remembers. Last night, Heather, a bottle of her rosé wine between them.
Still, from this angle, he can almost pretend he's gone back to the morning he woke up in Cassie's bed. This time, he won't get up quietly and leave before she wakes up. Instead, he'll wake her by covering her face with kisses and try to persuade her to call in sick to work and spend the day in bed.
He hears Heather sit up to turn off the alarm and can feel her turning to look at him. He closes his eyes and pretends to be asleep until he hears Heather get up and go into the bathroom.
