In one’s own misfortunes, also, one ought so to conduct oneself as to bestow upon them just as much sorrow as reason, not as much as custom requires: for many shed tears in order to show them, and whenever no one is looking at them their eyes are dry, but they think it disgraceful not to weep when everyone does so. So deeply has this evil of being guided by the opinion of others taken root in us, that even grief, the simplest of all emotions, begins to be counterfeited.
