Discretion has been termed the better part of valour, and it is more certain, that diffidence is the better part of knowledge.
The cruelest lies are often told in silence. A man may have sat in a room for hours and not opened his teeth, and yet come out of that room a disloyal friend or a vile calumniator. And how many loves have perished because, from pride, or spite, or diffidence, or that unmanly shame which withholds a man from daring to betray emotion, a lover, at the critical point of the relation, has but hung his head and held his tongue?Robert Louis Stevenson
Give me a mystery – just a plain and simple one – a mystery which is diffidence and silence, a slim little, barefoot mystery: give me a mystery – just one!yevgeny yevtushenko
