Brian, my sister Mardean, and I were in San Fransisco walking down the stairs outside of Ghirardelli Square. Suddenly, Rod McKuen came running up the stairs. There were no other people around and it was very exciting to see him. Mardean and I were big fans of his. He was gone in a flash.
Another time, Brian and I were having lunch outside at a restaurant in Malibu. We first noticed a lot of paparazzi around, then we saw Lindsey Lohan come out of a store and get in a car.
I’m not sure that either of these incidences really count as a famous encounter but they are as close as I’ve come to meeting someone famous.
