Today was a really hot day. After I had had my lunch, I went to the town square to watch a local singing contest. I went there alone. Arriving there, I chose a place under a big tree.

     I thought it could save me from the strong sunlight. I actually did not really pay attention to the contest. I just went there to avoid a boring time at home.

     Suddenly, I found myself behind a young boy. I was really sure that he was my classmate, Andi. I pinched him a little and called his name. The boy was surprised. When he turned around, I finally realized that he was not my classmate. I could not say a word. That moment was just embarrassing.
