Is the phrase <i>can be very unsure</i> correctly used in the sentence? Does it not sound cryptic? <br/><br/><i>Olga says, "Love <b>can be unsure</b>."<br/><br/></i>Would it be better if it is replaced with <i>might entail enormous uncertainties?<br/><br/><i>Olga says, "Love <b><i>might entail enormous uncertainties</i></b>."</i></i>
