Today is May 7, 2019. There are still 30 days before the children go to the examination room. Suddenly, I find that the year has passed like sand in my hands. The journey with the children is about to come to an end. I have cried, laughed, scolded, and was once loved by the group. The cute little fairy was once so angry that she turned into a hysterical dominatrix with distorted facial features. She always looked forward to seeing you go away, but she started to be reluctant to leave you at this time. She always wanted to... Leave something behind, record the pain, joy, laughter and tears of our youth, and leave behind the footprints we walked together. The sky will not leave traces of birds flying, but they have already flown. Success will not leave traces of tears, but I hope I can remember it for you.
