When I was in elementary school, there was an embarrassing experience I ever had when I thought about it. The experience was wearing shorts to school until grade 6. It is basically shorts that are allowed but with the passage of time and growth. The embarrassment began to come because all the students are wearing long pants / skirts. It is also required for new students. Imagine every day you become the center of attention and each class consists of 6 classes and 1000 students, it is really embarrassing and I do not want to experience it again.
