The elementary school years are over. My happiest day in elementary school is summer vacation. But it's also sad to be away from friends and dear school. But that's okay, next year we will continue with our dear school. With my dear friends.

Perhaps when we were in elementary school, all of us must have experienced even quarrels and fights with friends. In my late school years, there was a session that I felt most happy when I finished my exam and chatted with my friends. It was the last day of the party to say goodbye to friends. During that party, I ate a lot of delicious food and told stories of the past together. And I successfully confessed my crush. I felt it was the happiest day of my elementary school.
