Backyard Camping<br>John and his friends were camping in his backyard. Late that night, the boys heard a growling noise. A large shadow appeared on the tent door. The tent flap flew open and the boys screamed. John's father laughed hysterically at their reaction.
John's father could not have been the source of the growling noise and large shadow.
It's pretty obvious to a human that John's father was the likely source of the scare; I have no idea why this was hard for the AI.
