You we're on a long car trip, visiting some close friends of yours. An seemed really tired, she was slowly blinking and trying to stay awake. You asked if she was okay, and she said she'd be fine and not to worry.

Soon after, You felt a weight on your shoulder. An fell asleep on you. You lightly shake her -- but shes in a deep sleep now. You weren't sure what to do in a situation like this one.
