"Your brother?" St. Clair points above my bed to the only picture I've hung up. Seany is grinning at the camera and pointing at one of my mother's research turtles,which is lifting its neck and threatening to take away his finger. Mom is doing a study on the lifetime reproductive habits of snapping turtles and visits her brood in the Chattahoochie River several times a month. My brother loves to go with her, while I prefer the safety of our home. Snapping turtles are "Yep.That's Sean." "That's a little Irish for a family with tartan bedspreads." I smile. "It's kind of a sore spot. My mom loved the name,but Granddad-my father's father-practically died when he heard it.He was rooting for Malcolm or Ewan or Dougal instead." St. Clair laughs. "How old is he?" "Seven.He's in the second grade." "That's a big age difference." "Well,he was either an accident or a last-ditch effort to save a failing marriage.I've never had the nerve to ask which."
