Last month, I won a contest for a tour to Barcelona, Spain. It was a short tour but I was extremely pleased with it. I had unforgettable experience there especially when I visited the Camp Nou to watch the Barcelona football players practice. I saw one of my favourite footballers there. He's Lionell Messi. Then, the tour guide said that we could meet the players to take a photo and autograph. I grabbed my pen and rushed to Lionell Messi. He was surrounded by his fans but it didn't alleviate my plan to get his autograph. After a while, I finally got to close to Lionel. I asked him to take a picture with me and to give his autograph on my jersey. It was unbelievable and I almost wept because I was too excited about it. After that, we had lunch in a restaurant. Spanish people were very friendly. The next morning, after breakfast, we went to the airport and then flew to Indonesia.
