Falling in love at first sight can be bad in so many ways. You dont know who this person really is on the inside for all you know your just physically atracted to them. As far as Romeo and Juliette go, falling in love at first sight wasnt a good idea. Their parents hate each other and are always fighting. Juliette's supposed to get married to the Prince, but the thing is that she dosent love him. On Romeo's part I think he was wrong for going into the ball , where hima and julliette "fell in love." They werent supposed to talk to each other, they just went on about their lives disobeying their parents and just foucising on themselves.
