A Mark-shaped hole in the Universe....

I'm reading The God of Small Things, by Arundhati Roy at the moment and I wouldn't say that so far (p.119) that its the best book I've ever read; but there was a nice image painted on one page I've just read. It refers to Joe having been killed in a car crash and that there is now "....a Joe-shaped hole in the Universe...." Without wishing to be preachy, or morbid or anything like that I wondered for a moment if there'd be a Me-shaped hole in the Universe when I'm gone. Maybe in the shape of an old book or something! Probably not. Just a thought, what are we all here for and all that?....
