Facebook Adding A Sympathize Button?

About a week ago I liked a friends status.  The status read "Putting Jack to Sleep today.. He's been a great friend for the last 13yrs."  My friends dog was being put to sleep and I LIKED it.  AWKWARD!  I'm sure you've had a similar experience.  That's why I like this story.  Facebook is thinking of adding a "sympathize" button.  I think this is a great idea.   While they're at it I think a "dislike" button would be popular.  What other buttons should facebook add?
