I finished my dissertation and sent it off to my committee today. When I hit the send button, the thing that came to my mind was a scene from the end of The Lord of The Rings, when Frodo escaped from Cracks of Doom after the One Ring was destroyed. Frodo muttered "It's gone. It's done." with a blank expression. I guess I share the same feeling of relieve, only that I have to get it done before I can have it gone.
You lucky Hobbit really got off easy.
