Когда дружба начинает слабеть и охлаждаться, она всегда прибегает к усиленной вежливости.
В. Шекспир

давно не виделся, и пригласил его к себе в гости.
Отпраздновали встречу, всего было на столе вдоволь. Так
понравилось гостить, что кум о своем доме и не вспоминает. Как-
то вечером хозяин спрашивает:
-- А как же родственники, кум? Видать, скучают без вас жена
и дети?
-- Ваша правда, кум, ваша правда... Завтра же отправлю те-
леграмму... пусть и они сюда приезжают.
