How to write a critical letter without a school badge?

I left my school badge in * * *, which is very wrong. Because the school emblem is a symbol of a school, first wearing the school emblem is conducive to the construction of campus civilization. Students should devote themselves to the construction of campus civilization with a responsible and positive attitude, starting from themselves and starting from small things. Although wearing the school badge is a trivial matter, it is more helpful to improve students' awareness of prevention and clear sense of responsibility, so that students can truly feel that they have the responsibility and obligation to create campus civilization as a member of the school. Secondly, wearing the school emblem is a powerful measure to create a safe campus. A healthy and safe campus environment needs the joint maintenance of all teachers and students. Teachers and students should have the right to improve their awareness of prevention, be alert ideologically, deeply understand the importance of campus safety construction, strengthen their awareness and ability of self-protection, and effectively distinguish the actual actions of teachers and students in our school from those of outsiders by wearing school badges in their behaviors. In addition, wearing the school emblem is conducive to building a harmonious campus environment. A pure and harmonious campus is an ideal hall for thousands of students in Qian Qian to seek knowledge, and a beautiful dream needs our careful care. Wearing the school emblem can enhance students' sense of identity and belonging to the school and cultivate the spirit of collectivism. Only when teachers and students work together and cooperate harmoniously can we draw a harmonious landscape in the campus sky. So, I will never forget it.
