A
The house was quiet at 5 am and Tim’s mother was asleep. Only the sound of the big freezer broke the quiet. He’d dreamt of the cave last night. The purring (轻微颤动声) of the freezer had been the sea.
Tim pulled on a sweater and put some apples into his schoolbag. It was too early for breakfast. He’d eat after he’d been through the cave, sitting on the rocks and staring at the sea.
He wished he had a proper pack. His schoolbag would have to do. What else? Sandwiches-but his mother might wake up if he started pulling out bread for sandwiches, she' d want to know why he had to leave so early. He settled for some biscuits, and left a note stuck to the table: Gone to Michael’s. Back tonight, Tim.
The sky was high and soft and light outside, though the sun still wasn't up. Even the highway up the hill was quiet as he made his way down the street. The wind from the sea was fresh and sweet.
