I open the door, and before they get a chance to speak, I say: "Rai and Jiri at Lungha. Rai of Lowani. Lowani under two moons. Jiri of Ubaya. Ubaya of crossroads, at Lungha. Lungha, her sky grey." Then smile expectantly. They start to talk and after a moment I hold up a hand and say: "Kiteo, his eyes closed!". They usually give me a funny look and walk off at that point. If not, I wave them away, saying "Mirab, his sails unfurled." That usually works! It tends to be a couple of years before any come back.

SWMBO is more direct. She just says two words, the second of which is 'off'!
