A woman should say: 'Have I made him happy? Is he satisfied? Does he love me more than he loved me before? Is he likely to go to bed with another woman?' If he does, then it's the wife's fault because she is not trying to make him happy.
“All lovely things will have an ending, All lovely things will fade and die; And youth, that's now so bravely spending, Will beg a penny by and by.”
