The knack of being British is never to be drawn into unnecessary conversations under any circumstances. That rt is practiced from birth, a bairn’s first word is pointedly singular, and normally simply recognizes rank and number metaphorically.
Small talk in a wonderful aid to this national approved objective, allowing the expression of absolute nothingness in the interest of not appearing rude or offhand. A short exchange on the immaterial, the weather or a test match score fits the bill mot adroitly.
My enforced silence is the perfect cover.
