Advising Ophelia

Both Laertes and Polonius offer their two cents about Hamlet, but none of the advise given is seen as useful to Ophelia. Laertes  believes that Hamlet is young and ignorant, not knowing the meaning of love yet professing it to Ophelia and he also suspects that all Hamlet really wants is to make love, not be in it. Ophelia respects the insight given to her by her brother, but also states that he should not be one to talk because he too has done some of the things mentioned possibly. I can honestly say I don't know in what way Polonius attempts to advise Ophelia because everything she says to him he rebuts and continues a very long wordy response that seems to go nowhere but basically he is saying, he doesn't believe Hamlet is in love with her and I think he assumes that this is just a phase for Hamlet, as any young man would have for a woman.
