Treachery "Happiness may be destroyed not only by union with the man who is apparently the slave of interest, but with him whom a wild opinion of the dignity of perseverance, in whatever cause, disposes to pursue every injury with unwearied and perpetual resentment; with him whose vanity inclines him to consider every man as a rival in every pretension; with him whose airy negligence puts his friend's affairs or secrets in continual hazard, and who thinks his forgetfulness of others excused by his inattention to himself; and with him whose inconstancy ranges without any settled rule of choice through varieties of friendship, and who adopts and dismisses favourites by the sudden impulse of caprice."
