1. After driving for miles on a dusty road, you park your car
near the bank of a river and take a hike through the woods. Soon
you become lost. In one direction you see a small stream, and in
the other, a trail.
2. On a windy day you pick up the phone to call a friend, but you find that the line is dead. You live in a house and share phone expenses with a housemate.
