Thank you all for the prayers and positive thoughts you sent my sister. They seem to have worked. Karen is finished with the radiation and is now on the road to recovery. In fact, she'll probably get home before I do. I arrived in London this morning -- via Denver, Atlanta and Chicago -- and, even though I'm not a religious person, I've been praying for Karen every step of the way. In Denver, I sent God an e-mail from the runway, while watching a foot of snow accumulate and waiting for my plane to be de-iced. "Dear God," I wrote, "Please help my sister get through this, let her emerge happier and healthier than ever." The mail was returned moments later -- "undeliverable" according to the AOL Postmaster -- but I like to think it got through, nevertheless. And just in case it didn't, I high-tailed it to Saint Paul's Cathedral this morning, where I lit a candle for Karen and climbed more than 300 steps to the top of the dome to have a one-on-one with the Creator. I'm not Christian, but in times like these, I'm sure even Saint Paul would hedge his bets ...!
