There is a lot of anger between the two families. There's also a lot of killing in the story & between the two families. "Two households both alike in dignity (in fair verona where we lag our scene) from ancient grudge break to new mutiny" (prologue 1-3). This is say that the families are very much the same the families aren't really different, it's also saying what the family was fighting over turned into something new. It's sad the the montiques son and the capulets daughter had to die for them to realize that the fighting is stupid. "This by his voice should be. Montaque fetch me my rapier boy what dares the slave came hither covered with an antic face to the fleet and scorn at our solemnity? Now by the stock and honor of my skin to strobe him dead I hold not a sin. (Act 1 sc 5 52-58). Tybalt is saying he wants to kill Romeo and saying how he does not like Romeo.
When the two kids from the two different families first set Keyes on each other the instantly "fell in love". But I honestly think they don't know what it means to be in love.

Deny thy father and refuse thy name or if thou wilt not be but worn my love and ill no longer be a Capulet." Act 2 sc 2 36-39. Romeo & Juliet are willing to go against their families & friends to be together. "It is too rash too unadvised too sudden" (act 2 sc 2 118). This is said by Juliet she was starting to think that it was a bad idea then she changed her mind about what she said.
In the book Romeo & Juliet both betrayed their families to be with each other because they "loved each other." I think the trust that you have with your parents are most Important than anything in the world & I would have to break it. "Ah, Juliet If the measure of thy jay be heaped like mine and that thy skill be more to blazon it then sweeten with thy breath this neighbor air and let rich music's tongue unfold the imagined happiness that both receive in either Lou this dear encounter. (Act2. Sc6. 24-29). He's saying he's to excited for the marriage & wedding for words.
In conclusion, I thought that you can learn a lot from Romeo & Juliet. After you get by all the hard words it will actually get you thinking and get your mind juices flowing. Shakespeare is trying to teach us in Romeo & Juliet not to be so quick to love someone, betray your family or fight anyone.
