After a lifetime of minor finds at obscure thrift shops, Harriet thought she had seen it all. But when she got home with her latest haul and began to clean the small, oriental lamp she had intended to resell, she was astonished to witness a genie emerging from it.
"Look at you, so lucky," the genie said with a voice like bored cigar smoke hanging in an unventilated room. "I'll grant your three greatest wishes, but here's the thing: I'm in a real hurry, so you have 60 seconds to make the wishes before I disappear. Starting...now."
And that was how Harriet discovered that she had never, in her entire life, actually known what she wanted. The genie seemed to find that very funny as he dissipated into apparent nothingness.
