Can anyone think of a reason *why* this would be so, though? 

After rereading that passage in the book Nearly Headless Nick does 
say that "Wizards can leave an imprint of themselves upon the Earth, 
to walk palely where their living selves once trod". So I am taking 
it that Wizards have the ability to make themselves become ghosts 
they can choose wether they want to go on or stay. Nearly Headless 
Nick says he choose to stay behind because he was scared but that he 
doesnt think Sirius chose that. Talisha
