For my son the Supreme Conqueror Manifesting Auspicious Birth with Great Power of Speech, Eloquence and Persuasion (Ngawang Kezang Namgay).
In the animal kingdom in which we are just another subject, the role of the male species in the collective effort of procreation leading to the continuity of the world is little more than depositing sperm. Once that is done, the male becomes a father. Whether he has any other responsibility towards the development of his offspring or not, he still remains a father. Nothing can change the biological status once he has played his part as the depositor which in itself is an act that serves to fulfill his own basic carnal urge.
