You're sleeping at your girlfriend's house. It's 5:30 in the morning and the alarm is set for 6:30. She's snuggled up against you in a very pleasant position, but she's snoring like a chainsaw. If she rolls over she'll stop snoring and you can go back to sleep, but on the other hand the bed will seem a lot bigger and colder. Getting her to move and scooting over with her isn't an option because then you will start snoring.
Do you get her to roll over?
