У шамана спросили, какая будет зима -- холодная или теплая.
"Скажи им "теплая",-- рассуждает про себя шаман,-- не
запасут хвороста впрок, а вдруг будет холодная? Сразу прогонят!
Лучше пусть думают, что будут сильные морозы!"
-- Морозная будет зима, готовьте много хвороста! -- сказал ша-
ман, а сам решил узнать у метеорологов, какой у них прогноз на зиму.
-- Конечно холодная! -- ответили ему.
-- Ай, какие молодцы! -- восхищается шаман.-- А как ты уз-
нал, товарищ метеоролог?
-- Да что тут узнавать! Нет ничего проще! Иди сюда, посмот-
ри в окно: видишь, местный много хвороста собирают -- значит,
зима будет морозная!
