A Note to Thank a Friend for Helping You with Mathematics
May 11th Dear Li Mei, I want to express my gratitude to you for your selfless help, without which I would not be so confident about my mathematics in the midterm examination. Mathematics has always been a headache for me, but now I am quite confident that I will pass the exam. Many thanks again for your time and patience. Yours sincerely,Tom
