The gift of youth is a signature pen. Before the Spring Festival, Lieutenant Sun Gufeng received a video call from his mother, saying, "Before the Spring Festival, I cleaned up your favorite pen and put it away." The camera flashed across his mother's face and finally stopped at the corner of the desk. In the picture, a black signature pen lies quietly in the corner of the table. Its pen clip has been lost, and its transparent body is full of traces of time. This is a common signature pen, and is also the most familiar one for Sun Gufeng. Holding this pen, Sun Gufeng once wrote down the application for joining the Party one by one, and also signed his name on the new textbook with flying colors. After the phone call, Sun Gufeng's thoughts flew back to the Spring Festival a few years ago... Late at night, the light went through the window lattice, casting the shadow of "Fu" on the snow beside the road. In the study room of a company of an army brigade in the Eastern Theater, Sun Gufeng, who was lying on his desk, wrapped up his army coat and shivered. The air conditioning in the study room is not very awesome. Sun Gufeng's hands are a little stiff with cold, and his pen is also intermittent. The excitement of the Spring Festival seems to have nothing to do with Sun Gufeng. Seeing that the day for military academies to recruit soldiers for the unified examination is approaching, he devoted all his spare time to review. Turning over a page of the paper, Sun Gu Feng suddenly felt the light in front of him dim. He looked up and saw the monitor Wang Hongyun standing beside him, as if he had been standing for a long time. "Xiao Sun, give you a pen! This pen is my 'lucky pen'. I use it every time I take an exam. I wish you a smooth entrance to the military academy!" The squad leader zipped up his coat, took out a black signature pen from the pocket of his camouflage jacket, and smiled and handed it to Sun Gufeng, saying, "The writing is smooth, and the mood of review will be better." Holding the signature pen with the squad leader's temperature, Sun Gufeng felt warm. He carefully put the pen into the interlayer at the front of the pen bag. Since then, Sun Gufeng has always carried this pen with him, whether in the field or in the exercise. With the blessing of the monitor, Sun Gufeng became the first soldier of the company to be admitted to the military academy in recent years. Life in the military academy goes by quickly. Accompanied by this signature pen, Sun Gufeng opened a new military time. For Sun Gufeng, this gift from the monitor is not only a "lucky pen", but also the most unforgettable warmth. As time goes by, the pen has more and more scratches, and the pen cap has become loose due to frequent opening and closing. Later, Sun Gufeng took it home and treasured it. After graduating from the military academy, Sun Gufeng returned to the old company as platoon leader. That evening, he suddenly saw a familiar figure. "Monitor!" Sun Gufeng shouted. Wang Hongyun ran over and hugged him. Sun Gufeng was overjoyed to return to the old company and meet the old monitor again. The difference is that he has changed from a "runner" in the past to a "leader" in the present. At the Spring Festival party of the company, Wang Hongyun received a special gift - a pen from Sun Gufeng. Wang Hongyun knew that Sun Gufeng wanted to say to him, "In the future, we will write together.". Accompanying
