Dear Teacher,
I am writing to express my sincere gratitude to you. I used to be very shy and afraid to speak in public, especially in English class. I always worried about making mistakes and didn't feel confident.
When I was ready to give up the English speech contest, you noticed my hesitation and encouraged me not to fear failure. You spent your free time helping me practice my pronunciation and adjust my tone. You told me that my voice was unique and that I should believe in myself.
Thanks to your encouragement, I finally stood on the stage and finished the speech. Now I have become much more confident and am willing to take on new challenges. I will always remember your kindness and keep working hard.
Thank you again for everything you have done for me.
Yours sincerely,
A student
