Back in college, every time classmates or friends celebrated their birthdays, friends usually got together. First, they went out to eat together, then ordered food, and the cake was delivered. We laughed and shared the joy of sharing the cake. Finally, we sang or played ball. The meaning of birthday is to remind us that with the growth of life, we should learn how to maintain the friendship between friends from other people's birthdays! May friendship last forever and happiness last forever!
