It has been raining outside since early in the morning. Lena sits in her room and draws. The cat Fluffy is sleeping on the windowsill and purring. Lena is arranging her books on the shelf, spine by spine. Suddenly, one book slides out by itself. A small circular light shines behind it. Lena looks deep into the shelf and holds her breath. In the light, she can see a door like the blue of the sky. The door is round like the sun and quiet. Behind them the forest flashes and the sound of bells can be heard. Fluffy opens his eyes and speaks: Meow? Lena whispers: I think it's a portal, Fluffy. It's probably a portal to somewhere else. A leaf falls out from inside and smells of strawberries. Lena stretches out her hand, but the door pulls back slightly. A cry comes from inside: Hello, please help me! The voice sounds young and shakes a little. A small silver ladder appears on the threshold. The ladder sways like a boat on a wave. Fluffy jumps onto the ledge and wags his tail. Lena stands on tiptoe and touches the rung. Then a loud crack comes from the woods. The door begins to slowly close in front of Lena.
