Minuit quoque frequenter amorem stulti vesanique prolatio verbi. multi namque student in mulieris aspectu amentia verba proferre, se illi placere credentes, si fatuis et indiscretis sermonibus utantur; qui re vera mirabili deceptione falluntur. plurima namque sensus laborat inopia, qui dum stulta gerit se credit sapienti placere.
(Andreas Capellanus, De Amore 2.3.5)

The utterance of silly and foolish words frequently decreases love. Many men, when with a woman, think that they will please her if they utter the first silly words that come into their heads, which is really a great mistake. The man who thinks he can please a wise woman by doing something foolish shows a great lack of sense. (tr. John Jay Parry)
