Haunted.

Step-step-step through the halls, skipping on light feet. She seems out of place in this hollow and dead house. A bright red little red dress floats around her legs, it swings in time with her little hops.
The bright red bow in her hair matches the bright red of her dress. She is no one, just the memory of the house. They say she is a demon, a ghost returned from beyond the grave. Returned to haunt the barren halls and keep the spiders company.
The house was lonely, it used to be so full of life and joy. Cats purred on plush pillows, kittens played in the drapes. Children playing hide and seek, hiding in many small passages and holes.
It doesn’t miss the adults. They were serious and boring. Working their work, adding numbers and worrying. They had lost the joy of life. It doesn’t miss the dogs. It never even liked the dogs.
Skip-skip-skip through the halls, gliding through an empty hall. Starlight shines through dusty windows. The house was once the home of the great and the powerful but now it stands forgotten in an old corner of the city. No one comes here, no one lives here, it is a dead place.
The ghost of the memory of the house skips through the halls in her bright red dress. The bright red bow on her head matches her bright red hair. A ghostly kitten tumbles in her path and she bends, stroking it until it purrs loudly.

The house is lonely no more.
