My only love sprung from my only hate!
Too early seen unknown, and known too late!
Prodigious birth of love it is to me
That I must love a loathèd enemy. William Shakespeare–Romeo and Juliet

We recently watched Romeo and Juliet recently (the DiCaprio version), and I was reminded of my favorite line from the play. It also brought back a fond memory of my sophomore English Honors class–our teacher used to make us memorize lines from whatever play we were currently reading before he would admit us to the classroom. I remember enjoying memorizing this line, because I thought it was so powerful (and probably also because it was one of the few lines of Shakespeare I read that I could understand without thinking about and analyzing it!).
