Want to buy me a present? Of course you do.
The ideal gift for me is cufflinks or a big scarf or a colorful pocket square; fun, decadent, modestly expensive, and something I will surely use and enjoy.
I also really need a nice pair of slippers. I've accumulated several cheap and unsatisfactory solutions to the problem, and need to really solve it.
If you're feeling extravagant, there are three multivolume books I lust for: the unabridged McSweeny's edition of William Vollman's Rising Up & Rising Down, an unabridged edition of the Burton translation of The Thousand Nights and a Night, or the 11th edition of the Encyclopaedia Brittanica.
Or chocolate. Hard to go wrong with chocolate.
