Undear So-Called Father,
Since it has been confirmed by my analysis and judgement that you lack the competence, even the mere affection, to discharge your fatherly duties owing to your irrationality and irritability, and that you treat and control me whichever way you like like I were some small child, I have decided to abscond with what little money I can find.
The only regret I have for this action is the great deal of heartache it might cost my mother, whom you also maltreat. I want you to give her my word that I shall certainly fare well. Do not bother, the both of you, to search for me. I assure you that every effort to do that will prove fruitless as I have no need of further dealing with you, and am determined that it remains so. I shall, however, call my mother from time to time, as deemed convenient by me, to cheer her poor spirit up.
