Why I Love Artists: at Swimming Gal's birthday party, I was introduced to someone named Laetitia, who looked vaguely familiar. It took me a while to figure it out, but eventually it came to me: "Oh, you're the one who does that hand thing, aren't you?", I asked, as I wiggled a hand in the air. She smiled, "Yes, except it's the other hand", putting her left hand up & wiggling it the way I was wiggling my right (wrong) hand. Oh!
