In a block of flats on Cherry Street, the rain was tapping on the window sills. Hania was seven years old and liked to watch the drops race against the glass. The cat Migotek would roll over onto his back and catch the air bubbles, pretending they were fish. That afternoon, Hania opened an old drawer in her dresser. She found a cocoa tin. It smelled of cinnamon and dust after a long journey. Inside lay a kaleidoscope with a gold rim and a note: "Look when it drips from the sky. - Grandpa Tolek." Hania put the tube to her eye. First she saw the familiar, colourful stars. Then the image seemed to pull inward. Tiny houses, a market with umbrellas and an avenue of lanterns appeared. In one of the shutters someone was waving a white and blue handkerchief! Hania sneezed in amazement. Could this be possible? The next day, when it rained again, Hania looked into the kaleidoscope at different times. In the morning, the streets shimmered like fish scales. In the afternoon, leaves flowed down the gutter like golden boats. In the evening, the lanterns whispered and skylights rolled across the cobblestones like balls. Flicker, too, peeped into the tube with one eye and muttered quietly as if he could hear bells. One night the rain drummed harder. Hania could not fall asleep. The kaleidoscope was lying next to her pillow. Suddenly a sparkle slipped out from inside the tube. It fell on the wall above the shelf, sparkled and spilled like paint. Out of the bright dash sprang a door. It had a pane of rainy glass. Droplets swam inside, as if they were curious fish. The room smelled of fresh wind and warm sugar. Behind the door, quiet footsteps and laughter could be heard, barely visible as steam on the window. Tiny paper boats fluttered in the light from the threshold. One became entangled in Migot's whiskers. The cat sneezed and looked at Hania seriously, as if to say, "Shall we go?". Hania walked closer. She touched the frame. It was warm, like a cup of cocoa. At the level of her hand, a small handle, with a star in the middle, curled up from the glow. As Hania placed her fingers on it, a whisper flashed through the door: "Quick, the cloud parade is starting!". The flicker wagged its tail. A shadow in a striped scarf shimmered behind the glass. And then the doorknob itself, slowly, vibrated.
