I believe school uniforms should be mandatory in high school.

How do you think of the school uniforms? I wore that for six years. I believe school uniforms should be mandatory in high school: easy, privilege and symbol.
The first reason, I think school uniforms are very easy. For example, it is not necessary we choose own clothes. In the morning, I think of clothes what I wear. It takes about ten minutes. If there are school uniforms, I can use anything else for ten minutes. Also we can run comfortable. In the morning, I am very busy, so it is happy for me to sporty clothes.
Second reason, I think school uniforms are symbol. A high student is guessed the generation, so keeping a security.
