“Ah! You want to know why I hate you today,” the poet says. He then adds, “It will undoubtedly be harder for you to understand than for me to explain.”
The reason for the hatred ?

The poet and his female mate have passed a long day together promising each other that they would henceforth share all thoughts, and now on their souls would be one.

They are now in a new, sparkling café, dazzling and cozy with cabaret songs..

However the poet notices in front of them a worthy man of forty-odd, with a grizzled beard; tired looking, holding a little boy with one hand, while on the other carrying a tiny creature too weak to walk.They were all in rags.  “The six eyes,” the poet says, “stared at the new café with the same wonder, subtly differentiated by age…The ‘family of eyes’ makes the poet feel a bit ashamed of their glasses and decanters, much more than their thirst requires. He turns to look at his love in order to read his own thoughts in her.

But to his utter disappointment his love asks him: ‘I can’t stand those people, with their eyes like wide open gates. Couldn’t you ask the manager to get rid of them?’

The rest in the poet’s own words: ‘That’s how difficult it is to understand each other, my angel, that’s how incommunicable our thoughts are, even between people in love.’
