I got it was: Continue the story or change the ending.
“Because the mirror was sure to show the future, what was going to happen to each other or what they would be, and that could happen to Chacho in a skydiving accident.” David
“I once looked in a mirror when I was 12 years old. I wanted to be a pilot. I'm a boy and my name is Luciano. One day my mom told me that she had a big mirror left when they died. One day my mom pulled out that mirror it was dirty and dirty and I told my mom, if she wanted me to clean it up. I started looking at that mirror and when I finished cleaning it had a stain and I looked at me and it looked like an 18-year-old boy with a great age that you think of doing everything, that I especially wanted to be a pilot, looked at me and was in that mirror a pilot and I liked to look at me so many times that it seemed to be my future reality, looked at me was an 18-year-old boy. I was 12 years old and so I met Mom's fantastic mirror.” Antonella
“Chacho promised, but did not listen and continued to parachute, is more the parachute became his favorite toy and every day played with it. I got mad at him for not keeping his promise and we were in a fight for a while. Until what was seen in the mirror happened and I couldn't believe it, but that happened. I was a long time trsite for him. But when he got out of the hospital already recovered he said “you” don't tell me what to do and not do like you tell me I don't have to play with my parachute, so I'd rather you never talk to me again. And from that moment our friendship is over.” Oh, Mariana
“We thought that the mirror instead of being magical was cursed then...” “went to throw the mirror into a very distant field, when they arrived home they saw him in the same place and complete, well armed and were very frightened. From that day on Lila covered it with a curtain, because she realized that her story was unbreakable. Chan, chan... and... End”. Zunilda and Daiana
“We thought this mirror was cursed, so we threw it in wasteland. But when we got back, we found him in the same place where he was. We decided to cover it up and never look again.” Meital
“When they saw that the mirror showed them what would happen to Chacho, they thought of throwing the mirror far away where no one ever finds it.” Mariela and Alejandra
“Because something really bad could happen to them like dying or being paralyzed or some broken arm or leg and this has not failed now because of the promise I made to Chacho.” Ariel, Darius, Mark and Natalia
“After coming back in two weeks Chacho and he saw each other again in the mirror one at a time, first it was Chacho and saw nothing but his reflection and then it was him and he did not see anything but his reflection. Then the two of them decided that all they had seen was just their imagination.” Frank
“The mirror showed the boys how they were going to be in the future.” Micaela and Ayelén
“Years passed and Chacho turned seventeen, for me that day was key. Dad gave him a skydiving class and Chacho forgot his promise accepting the gift.
The next day Chacho was on his way to his classes and when I found him on the street and told him to remember the mirror. But since that was his dream, I would still go.
There's nothing to do anymore, Chacho was on his plane and it was his turn to jump.
The next day I find out that Chacho was hospitalized and when I arrive at the hospital I see the same image as in the mirror.” Axel and Gabriel
“They continued to go to Aunt Lila's house, but they were no longer near the mirror.” Braian and David
“When Chacho and Aunt Lila's nephew met for the first time, they ran out of there and ran home. After a few months they decided to return to Lila's house, they found the news that Lila had died. They made the decision to keep the “stained” mirror. Years passed, Chacho and Lila's nephew had their family, they forbade their children to look in the mirror so they don't have the same visions they had.” Leslie and Gisela
“Chacho never got on a parachute, but that accident that showed the mirror happened the same because when he left Lila's house he was hit by a car and what showed the mirror image happened. But soon after Chacho did not recover and died.” Vanessa
“Chacho never climbed on a parachute but that accident that showed the mirror happened the same. Because when he left Lila's house, he was hit by a car and what the mirror images showed happened. But soon after Chacho did not recover and died.” Michaela
