Useful

I bought a curio at an auction couple weeks ago. It's a beautiful little piece. It is supposed to be a French Boulle, but I think the auctioneer just put this description in to lure unwitting customers. I called and boasted about it to my ex-boyfriend, but first I had to explain to him what a curio is. He asked me "Is it useful?". I said, "Well, I use it to store my useless items, so in that sense it is useful".
