Sadie doesn't want her brother to grow up. She says that when she became 100 year-old doesn't want to die. The same thing she wants for her brother. She wants him to stay little, because doesn't want him to reach 100-year-old and die. Sadie is only 5 years and is thinking when she reaches 100. Really unbelievable thinking at her age, having in mind that these times many adult people doesn't think even for tomorrow. That is the main reason that this video has gone so viral.
