Nothing

Entering the kitchen, Olivia is expecting to see her parents, some fantastic breakfast, and maybe a graduation gift, but instead, she is met by a seemingly empty house; checking some other rooms, she finds no sign of her parents but does find a letter taped to the front doors' interior side.

Olivia: "What the... what's this? Where is everyone?"

Pulling down the letter, she reads it to find answers.

Letter: "Dear Olivia, We assume you are wondering where we are, Don't worry, we just didn't want to wake you after your day yesterday, but your father has been called away on a sudden business trip, and I've decided to go with him, we expect to be back in a month or so, we left money, and a list of things that need to be done in the envelope with this, call us if you need anything, and enjoy your summer sweety, Love, Mom."

Shocked, Olivia pours the envelopes' contents out onto the table beside her, finding five hundred dollars in twenties and a list of over a dozen tasks, some daily, like watering the garden, and some being one-time things like washing her mom's car. At the bottom of the list, "You have plenty of time, but this list better be complete when we return Oliva- Dad."
