This BOTD scenario is adapted from Pi Beta's story at MMSA:
A Pi Beta Production
This is your fourteen year old son's, Richard's, devoted bloodhound Bella. Richard dotes on Bella. One of his tasks before leaving for school for the day is to make sure Bella is secured in the back yard behind a gate.
On this particular morning Richard has a test in his first class of the day. You have been reminding Richard to prepare and study for the test but your warnings seemed to fall on deaf ears and so you told Richard, should he not get a passing grade on the test, that he would be punished. You and your spouse have left for the day but, on your way out, you noted that Bella was already secured.
Richard never prepared for the test and, fearing your wrath when he presented a failing grade, Richard concocted a plan to buy himself some more time. Bella's gate is secured with a sliding peg. Richard fashioned some similar pegs out of ice and left them in the freezer. (It was the freezer in the garage that neither you nor your spouse use that frequently.) Richard then used an ice peg to secure the gate timing things so as when the ice melted Bella could free herself. Why would Richard do this? (Also one wonders if he had spent all of this time studying instead of plotting could he not have passed the test.)
Richard knew exactly where Bella would go. Indeed, the ice melted and Bella ran free and, using her bloodhound senses, found Richard just as the test papers were being distributed. Bella burst in to the classroom and happily jumped on Richard loudly braying with excitement. Of course there was little choice but to have Richard escort his dog back home. Conveniently, Richard had missed the test. When asked about the test, Richard was able to truthfully tell you about Bella escaping, him having to bring her home, and how the test would need to be rescheduled for him. You knew the gate was secured but did ask Richard how it was Bella escaped.
Richard responded, "I dunno, I guess she just figured it out."
The next day you happen to need something from the freezer and find the unused ice pegs. When you ask Richard about the find the true story finally comes out.
How do you respond?
