Enter the White Door Room
You head right from the top of the stairs and approach the white door.
You notice that it is clean, the paint is in good condition, and the door handle is shiny. It’s pleasant. Much of the home echoes this cleanliness– the foyer was fairly spotless, the carpet on the stairs showed only the smallest stains and signs of wear, and the banisters were clean and not sticky.
(Sometimes, banisters are sticky, either from the presence of sticky-handed children or the use of improper cleaning supplies, but that is not so here. You can appreciate that you did not get sticky hands while climbing the stairs.)
