Electrical outlets

Rock's life depended on whether or not the oscillating fan in his bedroom was plugged in. If the people with the British accents instructed him to leave it unplugged, he would survive. Otherwise he would not. Whether or not Rock's laptop computer was plugged in bore on their instructions, but Rock was unclear how. He considered, and at last decided to leave his laptop plugged in. He never received final instructions from the British-sounding people, but chose to leave the fan unplugged and felt safe.
