"HERE LIES DOBBY, A FREE ELF.

I finished reading "The Deathly Hallows." Dobby's death is sadder when you read it again.  I love that Harry doesn't use magic to dig his grave.  While digging Dobby's grave Harry is finally able to clear his mind and Voldemort's presence is driven out.  Harry feels this is because Voldemort is driven away by grief, though its argued Dumbledore would reason love chased Voldemort away.  I think you can't feel grief the way Harry does with out having immense love for the person lost, and Voldemort can not comprehend anything other than hate, greed, jealousy, and anger.

Here is a quick illustration of what I think Dobby's grave looks like.

Can you relate to Harry's experience of being overcome by a single emotion so much so that nothing else can occupy your mind/body?
