In great danger of making enemies is the man or woman of brilliant wit. Sharp wit tends to produce a feeling of mistrust even while it stimulates. Furthermore, the applause that follows every witty sally becomes in time breath to the nostrils, and perfectly well-intentioned people who mean to say nothing unkind in the flash of a second ‘see a point’ and in the next second score it with no more power to resist than a drug addict has to refuse a dose put into his hand.
Emily Post on brilliant wit. Thanks to this Mental Floss list.
