We have a professor of psychology at the institute. He loved all kinds of myths and derived from them expressions and nicknames, such as the work of the Sisyphus, and you do not have a group here, but Augie's stalls, and in that spirit. One of his favorite expressions was - Buridan's donkey, well, this is when the donkey could not choose from which stake to eat his seed. At any moment when the student doubted - he turned his "Well what you stand, Buridan's donkey, choose already". Our stream learnt out normally, but in the flow of a year younger there is a student by name.... The Buridans. In my opinion, he will not go to psychology.
