Question: Two travelers have been traveling for a whole day. When they reach a hotel, they each get a room next to each other. During the night, one man couldn't fall asleep. The wall was so thin he could hear his partner snoring away. The man calls his friend, and when his friend answers, the man says thank you, hangs-up, and falls asleep. How did calling his friend help?
Answer: As mentioned earlier, the poor man could hear his friend snoring. When his friend answers the phone, the friend is not snoring anymore. Therefore, the man could fall asleep!
