<Should teachers always be kind and nice to student?>
Disagree

Body 1
TS1 - Strict teachers can control students better than kind teachers.
SS – When teachers cannot control their students, the classes become disorder. Teachers cannot continue their classes due to the disorder. However, strict teachers' classes are not disorder because students get low grades when students tallk each other.
AE - For example,my high school English teacher is very strict. After bell ringing, he locked the door, so other class students cound not go to there class. Also, the teacher's class students, who were not in there,  cound not come to his class.
