You're sitting on the passenger seat in a car, and your best friend, Evelyn, was driving. She opened the car window, so you decided to extend your hand out of the window.

When the car stopped for the traffic light, suddenly, a biker stopped next to your friend's car and held your hand.

"It's dangerous to extend your hand out of the window, miss. Put it back," he said, and then winked at you, before focusing on the traffic light.
