He [Hamlet] sees ghosts and listens to dreams. And....

“ He [Hamlet] sees ghosts and listens to dreams. And when his ghost father tells him that he (Hamlet Senior) was killed by his brother and asks Hamlet Junior to avenge his death, in the right, honorable way, Hamlet says yes, yes, yes, he'll do it. But somehow he never gets round to it. Not like the other two young men in the play. The Norwegian Prince Fortinbras(...) has made his life [!!] pursuing the honor that his father lost when Hamlet Senior beat him in single combat. (...). When the lord chamberlain,Polonius, is killed, his son, Laertes, returns to the court immediately, demanding restitution, (...). So there is no shortage of examples of how young men are expected to and do act in this world where honor demands an eye for an eye, a tooth for a tooth, a life for a life. But Hamlet doesn't do it. Instead, he beats up on his girlfriend and he's cruel to his mother. ”
