To me, the saddest thing about George was that he seems to have merely existed, while he was alive. From the article, he didn't seem to have any passions or ambitions. He didn't seem to want to go and see things, experience things, do things. He died in the same apartment, he was born in. He didn't really live, he just was, completely passive, until he wasn't.
At least that is the impression I got from reading this.
