My life in the four years of college was simple and monotonous, and the only thing that changed more than the classroom and dormitory life in high school was that I joined the laboratory.

Because of his good performance in the laboratory class, he was selected by the laboratory teacher as a teaching assistant in the electronic laboratory when he applied for the school's work-study program. Since the first semester of the sophomore year, I have been soaking in the laboratory every day, mainly to help the teacher prepare the equipment for class, help the students debug the equipment during the experiment, and then tidy up the equipment after the experiment. Usually when there are no classes, it becomes a paradise for me alone, of course, because I listen a lot on the side, and occasionally the teacher will help substitute the teacher when he doesn't have time. Especially when I didn't have classes in my senior year, I basically soaked in the laboratory every day, and my relationship with the family began at that time.

In my mind's eye, there are almost zero memories of starting a family, and no matter how hard I tried, I couldn't remember what it was like for us to meet for the first time. Every time he mentions it, he always gritted his teeth, lamenting that he was infatuated with a mistake, while thinking about the situation that day. The brain is a magical existence, although about the first meeting, my impression is all from the narrative of the family, but after listening to him for a long time, those blank memories are filled in by themselves little by little, and every time I think about it, it seems to become vivid.

The general situation is that the teachers in their school had something to do that day and asked me to substitute for their teachers. Their major is not electronics-related, just a minor, and everyone is not interested, and it is still noisy until the class bell rings. I don't know how long the bell rang, there was a loud clapping sound in front of the laboratory, Chengjia turned his head, and a girl stood in front of the teacher's experimental table, wearing a short ponytail, wearing a laboratory white coat, her brows were slightly furrowed, the expression on her face was a little cold, staring at everyone quietly. Seeing that everyone didn't react, the girl's expression was a little stiff, her brows were furrowed, and her mouth was slightly pursed, like a child who had been wronged. Probably sensing that his expression was not suitable, he immediately put away his little annoyance and a little helplessness, slapped him a few times, and said loudly: "It's quiet, let's start class." ”

In an instant, the laboratory fell silent, and later Cheng Jia said that in fact, many of the boys in their class were a little frightened by my somewhat cold expression at first. Suddenly the teacher was so cold, everyone didn't make much noise and began to listen to the class quietly. Later, I learned that this girl was a substitute teacher, it turned out to be the senior sister of the senior of the School of Physical and Electrical Engineering, and the family said that he didn't know what was going on, and he was obsessed with me from the moment he saw me, and the first thing he blurted out when he returned to the dormitory after class was: "I want this senior sister."

Chengjia said that my first feeling was always a little cold, but he didn't know why he was fascinated.

In the days that followed, I still didn't have much impression of Chengjia, and most of my memories of that period of time were told to me by Chengjia, probably because he went to the laboratory in advance to report every experimental class, watched me prepare equipment for the experimental class, and then occasionally asked me to help out under the pretext that I didn't understand the experiment. But because it wasn't their major, there was only one experimental class every two weeks, and because of my own personality, I retreated immediately after talking about the problem, so I really didn't have much chance to leave any impression on me when I got married at that time.
