In my memories, the Vietnam Teachers Day 11/20 is a day that I will never forget. It has left me with many interesting things and especially a memorable lesson. I was originally a pretty good student in the class, loved by my teachers, but I was commented to be quite cold and heartless. On November 20, I brought a large bouquet of flowers and a big gift to Ms. Yen - my class teacher. Everyone who looked at the gift had to admire the gift, I was very proud. Other students also rushed to give flowers to the teachers. Suddenly Nhi - my best friend said: '' Didn't you give gifts to other teachers? Why are you giving only Ms. Yen? ''. When I heard Nhi say that, then I sounded dissatisfied: '' Wow! What should be given to other teachers, teachers are just teaching subjects that are not given by the homeroom teacher. '' At that time, when Mrs. Yen never came close to us, when I heard that, she immediately came over to me and gently said: '' Why don't you give it to me, the teachers also have the merit to teach me I also have to know how to thank the teachers for their merit. If I behave like that, I'm a disrespectful student, you know? Look, like Miss Linh, she is just a music teacher that she is loved by the students, and is given a lot of flowers. That is the students' gratitude to her. '' Hearing her say that I feel stinging in the corner of my eyes, I blame myself for the reason for such actions. Without thinking any more, she rushed to the flower shop to buy lots of flowers to give to the teacher. Once done, I feel so proud and happy. That day was a day I could never forget.
