My face doesn't quite capture the utter shock and excitement I just experienced running into Novak Djokovic on Fifth Avenue! I slipped out of work to exchange a shirt I'd bought over the weekend (wrong size) when I saw this guy leaving Uniqlo who looked awfully familiar. I went right up to him and said, "Hi, Novak. What are you doing here?" He smiled, so I asked for a photo. Then his security guard tried to stop me, but I protested saying Nole had already consented to it. Novak sidled up to me, said cheese, and I snapped it. I then said congratulations -- I really wanted to say "How could you let ME down like this? -- and he shook my hand. Beaming, I went upstairs and they actually had my shirt in the correct size. I haven't been this happy since ... I ran into Roger Federer in a cafe in Rome!!!!
