Three hour pass. NO ONE knocks on the door.

The doll: Just a few more seconds. We might play "try-on-new-clothes" today.

Five hours go by. NO SOUND is heard.

The doll: Maybe the school bus is late. Soon she'll be here, and we'll sing and dance together.

One day has flown away. The doll is still sitting on the bed, waiting.

The doll: Maybe tomorrow… I'm sure she'll come tomorrow, and then we'll play.

There in the room, the doll repeats the same story every day…
