How does one enter a tea room?

Guests approach the tea room silently, and must hunch down to enter the three-foot-high door. This door, forcing everyone to hunch down, was meant to inspire humility. Guests gather into the room, all silent, and only when there is complete silence will the host appear. The only sound is the boiling water in the kettle. The kettle's bottom is made in such an uneven way as to produce a bit of a melody while water boils.
