"The Favor" (Part 1) (a story on my own) "I after I fell off the hill, I was lying on the ground in a very open zone. Then, I looked around to see if my friends were there but there was nobody else. I couldn´t remember how I got there, I just know that I fell off while I was climbing a mountain with Lukas, my friend. Even worse, I couldn´t see anything because it was too dark. Nevertheless, I could heard the relaxing sound of a stream. I couldn´t guess exactly where it came from, though it seemed to come from the north, so I trusted my instinct and started following it. When I was getting there, I had the feeling that I was entering into the woods, because I could hear the sounds of leaves being blown by the playful wind, which, by the way, brought with it a very sweet smell. I immediately knew that was the smell of mint, so I got exited and I went deeper and deeper into the woods to follow the redolence. Unfortunately, when I was walking through, for about 2 minutes I lost the mint essence; I was too bad at trusting my nose, so I couldn´t find anything. However, I got the stream. I was thirsty, so I used my hands to drink from the water. I felt great, because it was sweet and fresh. After that, I lifted up my head, and I saw a man in black who asked me to do him a favor. His voice was shaking, and he was pale. He said that this favor could change his life, and also mine..."

Why parrots can repeat words (pourquoi story I created by my own) 3000 years ago, human beings and parrots lived together in an enormous region named “The magic paradise.” Parrots were taller than human beings, even though they were stronger, and able to fly. Men and parrots belonged to different lands within the region, but they used to meet, and do businesses. They lived in peace for a long time, but one day, a woman named Claire, who was married to the leader of the land she belonged, met a parrot, and fell in love with him. A few days later, the leader of the human land found this, and said: “I cannot accept it! I want him, and all the parrots to be punished!” Then, he hired a witch to put a curse on all the parrots´ land as revenge. The curse consisted on making them unable to communicate with human beings forever. Instead, they would be only able to repeat the sounds the humans produce but without understanding them. And that is why parrots can repeat words from people.

A joke that went wrong When I was 13, I bought a gelatinous toy at school that I used to play jokes with. I used it everyday during the hole 7th grade. It was very funny, but at the same time annoying for my classmates. I remember that was a large sticky frog-shaped toy, and it had a line that connected it to my hand, so it would never slip from my fingers. One day, I threw it into my teacher´s classbook, and I broke some of its sheets. (It wasn´t on purpose, I just failed, the joke was for my classmate) Angrily, my professor yelled at me. As a result he called my parents, and they argued with me. Finally, I was prohibited to play with my toy anymore.
