You were reading your book and then suddenly you heard a knock at your door. Your older brother opens the door and leans inside.

"Hey, mom and dad said they are going on a business trip so we'll be on our own without them for a week. You better behave." he says sternly, his eyes fixed on you.

"Mom and dad said I will watch over you." he says with a sigh as if he suddenly has a responsibility and more work put on his shoulders.
