So, someone at work is renting a room in a town 20 kms away and has agreed to provide you with a ride to work everyday (you don't have a car) if you take it and are willing to split on gas. During the first ride, they mention that it's not a problem if you fall asleep. You don't want to fall asleep because you want to be there to provide conversation for your drowsy driver. But, it's possible that they want you to fall asleep so that they can gossip about how you fall asleep every morning while driving to work. What do you do?
