I would to say for you some words inside my heart since along time, my teacher thank you alot for what you doing ,it's great and serious for the whole world,your job needs to brought and taught your students in the same time, you are a role model for many generations ,but this is difficult no person can be a teacher just who has intelligent brain and wisdom of strict. When I was child my parents said to me you should love and respect your teacher,and my mother said " I am a slave to those who tought me to read ", then I memorized this wisdom since my childhood to now.
The taecher has value position we must appreciated him. thank you teacher again and the God take cear of you always .
