Hehe, your story reminds me of my fate with mathematics. Before the fifth grade of primary school, I was the most common one among many students. The head teacher of grade five is a math teacher. I remember one time she posted wallpaper in the dormitory, and she specially asked me to help her look at it. Wind chimes will be popular, so she asked me to help her cut paper. Gradually, I like math, because I think teachers will trust themselves more. Until the sixth grade, the math teacher was a master and very serious, but every time I asked him a question, he was always very serious.
