An 18-year-old's answer

When I occasionally walk through the alley there, the hollow and heavy chimes hit my heart forcefully. What ripples are the annual rings of time, one circle, two circles... eighteen circles. He reached out and grabbed his chest habitually, only to catch the air and run away in a hurry, only to find that the red scarf, nicknamed "dried radish", was no longer there. A sense of futile loss suddenly fell, hitting my shoulders and shattering my heart. Yes, this year, I am eighteen years old. Eighteen years old who is preparing to take the college entrance examination.

Overbearing clouds cover the sun tightly, and sparse patches of color slip through the gaps in the clouds, blurring the treetops, and mottled the bluestone slabs with crisscrossing ravines underfoot. Every day, I shuttle between two points and one line like a mechanical machine. Wandering among the noisy petrified forest, the harsh mechanical voice seems to be screaming "College Entrance Examination! College Entrance Examination!" Once upon a time, I set up a drawing board to sketch by the river, depicting the colorfulness of adulthood at the age of eighteen; Once upon a time, holding a camera, Running around the streets and alleys, capturing every moment of eighteen years of growth. Now, the eighteen-year-old "I think" has become a pavilion, and the eighteen-year-old "sky" has been shelved. I mechanically thought that my life had lost its color and had become monotonous black and white. For example, the only focus of a thin film is the college entrance examination. I began to miss the joy of the past uncontrollably, but quietly let the happiness drift away. I thought that life at the age of eighteen was like a slogan, lived in rhyme and obedience.

That day, I was still rushing home. Urgent and aimless, contradictory and anxious. In the park, people in twos and threes are relaxing or relaxing, which distracts me from my irritability. Suddenly, a loud and brisk whistle sounded from behind. I followed the sound and saw that it was a little older primary school student. He smiled shyly at me, with a warm arc at the corner of his mouth. He jumped lightly in front of me, shook his little head and asked shyly: "Sister, do you think I play well? Why are you frowning and unhappy? Let me teach you how to play!" with chubby little hands. He caressed my eyebrows, as soft as coal, warming my heart. The soft palm line flattened my raised eyebrow line. "Like this" he pouted and blew vigorously. I followed his example carefully, pouting my mouth high, but I could only smell the rapid flow of air and sigh. He laughed so hard that he laughed and proudly corrected my movements, as if he were a little adult. My heart was instantly overflowing with joy.

Even the clouds were smiling from ear to ear, letting the sun slip out wantonly. Our laughter distorts the light and makes it grotesque. One middle school student's school uniform and the other an elementary school student's uniform fit so well. The two disheveled heads swayed together and burst into laughter. This is the life of an eighteen-year-old.
