Good for You My sister and I would dare each other at the dinner table, once we sucked the chicken from the bone, to eat the white knuckle-joints. There's a bump on the roof of my mouth where I cut my gums trying to win. The last to the marrow had to eat it.   It's good to know true hunger. It's good to let your body get so hungry that you remember you're nothing special. You're nothing but a break-it-down machine. Standing in line at 4am in the Hong Kong airport waiting for a bowl of something you can't identify, 37 hours since your last meal, it's good to miss the taste of bone.   Molly Prosser Molly Prosser (molly.prosser@gmail.com) is always Mrs. Peacock in Clue.
