The happiest thing about childhood should be those beautiful memories that let us still feel warmth and happiness when we grow up. The following is an essay that I have written for you. I hope it will meet your expectations. One of the happiest things in my childhood was going on a picnic with my friends. Every summer vacation, we would plan where to go and bring all kinds of food and drinks to spend a pleasant afternoon together. We usually choose a park or open space and prepare food and drinks. We'll divide the food into small groups and each person will be responsible for preparing different food such as fries, fruits, biscuits, and so on. Then we put the food in plastic bags, put on life jackets, hats and gloves, and have a picnic. During the picnic, we would play all kinds of games such as guessing riddles, hide-and-seek, throwing sandbags and so on. We would also chat and share our stories and experiences, encouraging and supporting each other. We'll be laughing all afternoon and won't be home until dusk. Although every picnic was short, those beautiful memories would always remain in our memories. Whenever we think of that afternoon, we will feel warmth and happiness. I believe that was the happiest moment of my childhood.
