Dear [Teacher’s Name],

I hope this letter finds you well. I am writing to explain my abrupt departure from the course and express my gratitude for the invaluable experience you provided.

Regrettably, I had to leave the course unexpectedly due to a family emergency back home. The situation demanded my immediate attention and required me to fly back home to be with my family during this challenging time.

Despite my premature departure, I thoroughly enjoyed the part of the course I was able to attend. Particularly, I found the interactive discussions and practical exercises to be incredibly insightful and enriching. Your teaching style and expertise truly made the learning process engaging and memorable.

I would like to extend my heartfelt thanks to you for offering such a valuable course and for your dedication to fostering a conducive learning environment. Although my time in the course was cut short, I am grateful for the knowledge and skills I gained under your guidance.

Thank you once again for your understanding and support. Warm regards,

[Your Name]
