HOUSTON, Nov. 18 (UPI) -- Former President George H.W. Bush entered the room from the right front of the stage, with former first lady Barbara Bush close behind. "Do I know you?" she said to me with a Cheshire cat grin as she walked by and sat within earshot and kitty-corner at the neighboring table. "We met in Prague some years ago, ma'am," I said. "Beautiful," she said. "We'll have to talk." And she sat down. It was the gala of the American Friends of the Czech Republic at Houston's venerable J.W. Marriott hotel last week.
