A couple differences between today and the time of Romeo and Juliet, would be age. Romeo was most likely much older than Juliet. Also in the Renaissance, loyalty was VERY important to them. (Something they kept from the middle age when people lived on lords manors) The loyalty of the Capulet and Montague was a huge thing...Use the example of Juliet's monologue when she says "a rose called by any name would smell as sweet, as would romeo were he not romeo called."
