Have you ever noticed, when old friends get together how they begin to talk in shorthand and their words blend, sentences and grammar become irrelevant, and in some instances, a mere word, gesture or phrase will send them into gails of laughter as they remember some indiscretion of one or another of them and how they handle it with the respect it deserves and how someone always ends up laughing longer and harder and this often sets them all off again and then when the laughing is done, they all seem to glow with the shared joy of old friends?
