According to Freud, an individual's behavior is determined by the inner conflict of the 3 components of the personality structure: Id, Ego, Super Ego.
Let's break them down:
Id: the most primitive, it represents one's desires and instinctive behaviors. It would be saying "I want this now".
Ego: the mediator between the id and super ego. It deals with reality and it helps the individual bend more to that is <em>acceptable by society. </em>
Super Ego: it represents moral and ethics, understanding <em>right from wrong. </em>
In this case, the <em>Id is taking charge</em> since your friend is showing you the desire and urge of going out to drink and have fun, even if he has responsibilities for the next day.
