Romeo and Juliet- I'm only using this because I just read it.
The ending of "Romeo and Juliet" was nothing but ironic. When Romeo shows up to Juliet's tomb, Paris is there paying his respects to the woman he was suppose to marry. Instead of Romeo and Paris fighting resulting in Paris's death, Romeo could've waited a little longer to go to the tomb, because the Friar was on his way to wait for Juliet to wake up. If he waited, He would've known she wasn't really dead, and they could have actually ended up together and forever in love like they wanted.
