VIDEO : J.K. Rowling has apologized for killing off Dobby ? and everyone is exhausted

It's the 20th anniversary of the Battle of Hogwarts, the climax of the "Harry Potter" series in which many beloved characters were killed. Rowling takes to Twitter to apologize for killing off a character. This year, she apologized for killing off Dobby, a house elf who died to save Harry, Ron, and Hermione before the actual battle took place. Some are beside themselves and appear to be mourning the loss of Dobby all over again. Others are frustrated with Rowling's repeated amendments to a series that she finished writing over 10 years ago.
