When I was in primary school, I was a boarding student since my school is far from the place where I live, and I had never thought about that I would meet my primary school classmate. But it just happened, Back to the time when I was a freshman for middle school, I attended the flag raising ceremony, and somehow I noticed that a girl standing next to the girl in front of me looked like my classmate. I didn't think that it would be coincidental enough for me to meet my primary school classmate, especially my primary school was so far away from my middle school. But after the flag raising ceremony was closing to the end, she turned around somehow, and I could see that she was exactly my classmate from primary school! I was so surprised and also delighted to see her around. She also recognized me, and waved her hand to me. After the flag raising ceremony, we headed back to the classrooms, and we chatted for a while in the corridor. This is such a happy coincidence.
