"Rick Davidson" Mr. Sir exclaimed. "Yeah." Rick replied. "Where is your homework?" Mr. Sir asked. "Oh! I don't have it Sir." "Why not?" "Well," Rick began, "I was walking to school today when suddenly a time traveller from the future leapt out in front of me! He was covered in battle scars and had a torn piece of paper in his hand. I recognized it immediately. It was that very piece of Spanish vocabulary that you had given me on Friday! The time traveller explained that if I handed in this homework then worms would take over the world!" "I had to do something about that so I called some giant moles over and told them to dig a mile deep hole in the park so I could bury my homework. Unfortunately, one of their elders had a sore paw and you've always told me to respect your elders so I had to run all the way to a military base and arm-wrestle someone to get a nuclear missile to create a hole deep enough to bury my homework." "But when I returned to the park the nuclear missile went off because of Miss Devonshire's horrible perfume! I was shot thirty meters into the air before plummeting to the ground! Luckily, I opened my rucksack and it turned into a parachute and I drifted to safety." "Unfortunately, all off my books had fallen out of my rucksack and had drifted into the Atlantic Ocean, along with my Spanish vocabulary!" Rick finished triumphantly. The whole class was silent. Mr. Sir looked at the boy, his eyes tiny slits inside their sockets. "Well, your story is definitely intriguing Mr. Davidson but I don't believe you." Mr. Sir spat. Rick searched about in his bag until he came to a burnt piece of paper. "Here is the sheet the Time traveller gave me. It's a little soggy because my water bottle leaks and it is now in the Atlantic Ocean BUT that's all the homework I've got." Rick explained, handing the sheet to his stern teacher. Mr. Sir looked at the burnt sheet in his hand. Carefully, he un-crumpled it and stared at it. Indeed, it was the Spanish vocabulary sheet he had handed out on Friday!
