Sshhh, children, don't let those noises frighten you. Old houses always harbour strange noises. Noises won't hurt you.
Those sounds could be footsteps but they're far away, down in the entrance hall. Sometimes they're closer, so loud you'd think they're just about to enter this attic. But don't fear them. They never stay long.
The whispering won't hurt you either, my darlings. They always whisper.
All those noises, the footsteps, the whispering, they won't harm you, my children. Hush now, don't fear them. It's only them doing what they enjoy. It's only the living, come to explore a derelict building.
