"Anyone who doesn't read Cortazar is doomed.  Not to read him is a serious invisible disease which in time can have terrible consequences.  Something similar to a man who has never tasted peaches.  He would quietly become sadder... and, probably, little by little, he would lose his hair."

-Pablo Neruda

Apparently the guy was a friend of Borges, heavily influenced by him, used a lighter style.  I just picked up one of his short story collections, Cronopios and Famas.  From page 6, entitled "Instructions on How to Cry":

Putting the reasons for crying aside for the moment, we might concentrate on the correct way to cry, which, be it understood, means a weeping that doesn't turn into a big commotion nor proves an affront to the smile with its parallel and dull similarity.  The average, everyday weeping consists of a general contraction of the face and a spasmodic sound accompanied by tears and mucus, this last towards the end, since the cry ends at the point when one energetically blows one's nose.

In order to cry, steer the imagination toward yourself, and if this proves impossible owing to having contracted the habit of believing in the exterior world, think of a duck covered with ants or of those gulfs in the Strates of Magellan into which no one sails ever.

Coming to the weeping itself, cover the face decorously, using both hands, palms inward.  Children are to cry with the sleeve of the dress or shirt pressed against the face, preferably in the corner of the room.  Average duration of the cry, three minutes.

The next page is titled "Instructions on How to Sing".
