作文_7B_A thank you letter

Dear Tom,

I sincerely appreciate your generous help. Your patient guidance not only helped me solve those challenging math problems but also taught me how to approach them logically. Thanks to your support, my teacher has noticed my improvement, and I now feel much more confident. Words cannot fully express my gratitude, but please know your kindness means a lot to me. I look forward to our continued friendship and hope to return the favor someday.

Warm regards,
[Your Name]
