Last Sunday morning, when I was having a walk in the park near my home, I came across a crew make a new film with one of my favorite actor. I didn’t bring my camera with me at that time, but I rushed back home to get. Unfortunately, by the time I got back, they have finished the scene and the actor could not be seen everywhere. I was really disappointing and about to leave when he walked out a building. He was right there in the front of me. I couldn’t believe my luck--- not only did I had my photo taken with him, but he signed his name on my shirt.
