There are several, but now I remember two. One is about my birthday. My birthday is August. When I went to school, I couldn't invite my friend to my birthday party because it was summer vacation. And when I was a university student, I had to go back to my dorm to prepare for the memester. So, I always felt sorry for my birthday. But when I was in high school, my friends called me to an empty classroom and gave me surprise birthday party. I was surprised and I was happy that my friends congratulated me on my birthday. The other is about my younger brother. When he was in the army, he came back home for his vacation without telling our family. When I saw him coming home, I was surprised, so I sat down on the floor, and I cried a lot. He didn't expected my reacation, smoothed me. But I told him. "What a suprise vacation! It's good to surprise our family, but don't do this again. I almost died of a herat attack now."
