People should let things go
Act 1 Prolouge
In the story of Romeo and Juliet the text tells us,"In the prologue, or preview, the narrator explains the play will be about a feud between two families (the Capulets and the Montegues)" (p.922 lines 0-0). This feud has lasted a long time between the two families and it had never been let go. Since the feud was never let go, both families suffered consequences like the death of Romeo and Juliet, or the death of Tybalt.
Act 1 Scene 1
During a huge rumble in a courtyard between the Capulets and Montagues, Lord Capulet yells to Lord Montague,"My sword, I say! Old Montague is come, and flourishes his blade in spite of me" and Montague responds,"Thou villain Capulet! Hold me not, let me go" (p.5 lines 67-69). Due to Lord Capulet or Lord Montague not letting the feud go they are now enemies to each other. If they would've let things go and just decided to be ok with each other then they would not be enemies of eachother.
Act 3 Scene 1
When Romeo and Tybalt confront each other in a courtyard talking Tybalt says to Romeo,"Romeo, the love I bear for thee can afford no better than this: thou art a villain" (p.3 lines 31-32). Tybalt is a Capulet and Romeo is a Montague, and because of this Tybalt automatically feels that Romeo and him must be enemies. If Capulet would have let the feud would've been let go, the two wouldn't be enemies, but maybe friends.
Act 2 Scene 2
When Juliet was standing on her balcony talking to herself she said,"O Romeo, Romeo! Wherefore art thou Romeo? Deny thy father and refuse thy name! Or, if thou wilt not, be sworn my love, And I'll no longer be a Capulet"(p.1023 lines 35-38). Juliet knew she fell in love with Romeo, but he was a Montague so she would not be able to date him. If Juliet would have accepted the fact that she would not be able to be with Romeo and moved on to find another man, then all the deaths and consequences that came about would not have happened.
