Wait 'Til You're Older

Reha despises the present, all because her brother says he won't let her play with his dinosaur toys until she's older. To solve this problem, she decides to build a time machine. But even though she does everything her time travel book says, she can't seem to get it right. Then in her last attempt to find what she needs, her brother asks if he can help. Perhaps the present could be okay after all?
