..to laugh is proper to the man.

She's a good-hearted woman in love with a good-timin' man.
She loves him in spite of his ways she don't understand.
With teardrops and laughter they pass through this world hand in hand,
A good-hearted woman, lovin' a good-timin' man.

It is — or seems to be — a wise sort of thing, to realise that all that happens to a man in this life is only by way of joke, especially his misfortunes, if he have them. And it is also worth bearing in mind, that the joke is passed round pretty liberally & impartially, so that not very many are entitled to fancy that they in particular are getting the worst of it.

Because if a woman's heart was free a man might have hope.
