I am so exciting that I can’t wait to share with you what I experienced today. I gave my first lesson in our school, which left me the deep impression.

When I entered into the classroom, my students began to make much noise. I stood on the

platform, knowing what to do at first. But soon I realized everything must be done. I asked the

kids that they liked English songs. They all say “Yes.” I sang a song I had practised many times.  To my great surprise, all the kids turned their attentions to my class.

From this experience I know however happens, we must stay calmly first and find a wise solution.
