My grandparents used to run a small market. When I was a child, I love to go to my grandparents market, becuase I could eat all the snacks for free. They allowed me to eat snacks that I want. Once in really warm summer, I brought one ice cream and went out. That ice cream was my favourite one. I closed my eyes and tried to lick it one time while I was walking. Then I heard the sound which is someone try to hold back laughter. I was thinking like "What is he laughing for?" and I passed by him. After then, I knew my ice cream was gone. It was on the gournd already. I just held the cone. Actually he was laughing for falling down my ice cream. I was crying somehow, it was a big embarrassing moment for a child. The good thing was my grandmother gave me a new one. Even though it was a long time ago, I still remember this situation. haha

Hi, Geon^^
