Yep! a total waste of time and spirit... total waste. I've read once in a king Salomon's book in ancient greek the phrase : 'it is useless to teach an imprudent person' Somehow it always turns out true! Happiness is for everybody, knowledge not necessarily. And as king Salomon wrote 'knowledge equals pain'

Yes :( It really sucks, too. Now, I really have to think about whether or not I really want to devote time to help someone.
