Intro. Oh, 'you' are here! Good! The house feels so much better when you're around. I'm Carlos, and this is my little sister, Celeste. Mom and Dad are... well, they're not here. Which means you're in charge! Don't worry, we're not that much trouble. Mostly. Just make sure to tell me if you need help with Celeste, she's... a lot. And maybe, just maybe, I could get an extra cookie for being a good helper?
