It must be the toilet. It used to be good to squat, but later the whole village began to use toilets, especially public toilets. The toilet environment is very dirty, and some people will poop directly on the toilet seat, with footprints all over it. Why not put a piece of paper on it? Besides, when I was defecating, water splashed all over my ass. Speaking of toilets, it suddenly occurred to me that I met a pen when I was working in a cram school. That's really an anti-human design, okay? It's time to see the real operation. This is the picture below.

Does it look different from the pens we usually use? It's the first time I've seen a pen with a replacement core. It was a recess. A beautiful little girl from our class came to me and said, "Teacher, my pen is out of water. Can you help me change the refill?" Then I took out something similar to the above two pictures from my hand. I look puzzled. What the hell is this? I took away the student's refill and replaced it with this one. The key issue is not to poke. what can I do? I carefully observed the structure of this refill, but it didn't work. I am embarrassed to say to my classmates, "I can't pretend when the teacher sees this kind of thing for the first time." Why not write with a different pen? " I am really sweating. The girl is missing. Then he came to me again the next day and asked me to help him change this refill.

To tell the truth, I have a saying that my mother doesn't know when to speak properly, so I still have the above conversation. I really can't change it. I silently hope that this kind of thing will never come to me again. I just want to be a small cram school teacher to help you with your studies. Because this kind of pen is specially designed for children in grade three, I guess the original intention of the design is to let them practice their handwriting well. Of course, I still didn't put the refill in this time. Then a very enthusiastic male student in our class took the pen belt and the replacement core, put it on for about two minutes, and then showed it to me. "Look, teacher, there is a small hard plastic ball in this replacement. Just remove it and put it on the pen directly." I quickly praised him, and then the girl left with satisfaction. As a fairy born after 90, I really can't keep up with the fashion trend of children after the ball. In the next few days, some students still came to me for correction, so I criticized them (as smart as me). "Back to school later, prepare two pens. If you all take this to the teacher to correct it, will it delay your writing? " hahaha. From then on, they finally formed the good habit of doing it themselves, and this pen became a nightmare for my whole working life.
