Birds explanation

The explanation of the birds by Antonio Lobo Antunes ... We were in the farm when suddenly a flock of birds flew from above the chestnut tree near the well, towards that spot in the forest that turned blue at the beginning of the night... The wings fluttered with the rustling of leaves moved by the wind, small leaves, delicate, numerous, like dictionary pages, Conth held your hand, and suddenly asked you explain to me what are the birds... Just like that, nothing more than that, explain to me what are the birds, an awkward request for a businessman but you smiled and told me that their bones are formed from sea foam, and that they feed on wind crumbs and that, when they die, they float with their backs up, their eyes closed like elderly women during the Eucharist.
