Hi Patrick,
How are you now? Hope you are fine. I know you are very good at Maths, aren't you? Now, I am doing my homework but this question is so difficult that I cannot do it. I cannot do it because at the time my teacher was teaching my class this lesson, I stayed at home because of my sickness. Can you help me with this? If yes, we can meet at the library near your house.
If you agree, please write to me soon.
Hope your letter
Best wishes,
Vy
