Dear Mr. Evans, I am writing this letter to apologize for not being able to attend the British History lecture tomorrow afternoon. I am sorry for causing any inconvenience. The reason for this is that my father has to travel to Beijing on business and my mother is hospitalized due to illness, so I need to stay at home to take care of her. I am wondering if the lecture will be recorded. If so, I would like to listen to the recording if possible, in order to make up for the missed lecture. Once again, I apologize for not being able to attend and I hope you can understand my situation. Sincerely,
Li Hua
