All men have a feeling, that they would rather you told them a civil lie than give them a point blank refusal.... If you make a promise, the thing is still uncertain, depends on a future day, and concerns but few people; but if you refuse you alienate people to a certainty and at once, and many people too.
Any man may make a mistake; none but a fool will stick to it. Second thoughts are best as the proverb says.
[Lat., Cujusvis hominis est errare; nullius, nisi insipientis, in errore perseverae. Posteriores enim cogitationes (ut aiunt) sapientiores solent esse.]
The mind becomes accustomed to things by the habitual sight of them, and neither wonders nor inquires about the reasons for things it sees all the time.
