At night I was studying to become a certified electronics technician at a vocational school. One day someone from the staff told me I would be barred from the exams because I haven't paid tuition (a month after this the school was incorporated by a state-owned university and went tuition-free otherwise I would never graduate). So picture a mother that will steal tuition money from his son and you can imagine how my mother leeched me for years. This kind of abuse has consequences for life.
Sometimes your parents are very bad people and there is nothing you can do about it. And no, I don't really care if either of my parents live or die, in some way they are already dead for me.
