"Once upon a time, in a faraway wood, a family of colourful birds made their home..." one of the nieces begins her story as she makes the scene come alive with the chalks in her hand. Riveted, Anna and Clara, the nephew, and their other niece draw nearer to hear the fantastical tale to be spun.

"Children truly have the most marvellous ideas," Anna whispers to Clara with a smile as they both lean over to get a good look at the niece's artwork.
