Dear Dayana Andreevna,
I am writing to let you know how grateful I am for all your support and guidance throughout my time in school. Your passion for mathematics and dedication to teaching have truly inspired me, and I feel fortunate to have had you as my teacher.
As we move on to new adventures after graduation, I hope we will keep in touch. I would love to share my future experiences with you and hear about your ongoing work in the classroom.
Thank you once again for everything. Wishing you all the best!
Sincerely,
