Dear Ms. Reinhart,
I am terribly sorry that I failed to arrive at BLCU last Friday. I hope that this did not mess you up completely, although I know that you had already made some special arrangements for my visit with you parents and friends. I am very sorry about all that. I am sure you will be sympathetic, however, when I tell you that my father is dangerously ill in hospital, and that I found it impossible to leave for the visit when he is in this state.My father was working very hard on his project on protecting the environment. I know the project has come to a very important stage. He and his assistants did not take regular rest for three weeks. Last night, my father had a heart attack and was soon sent to the hospital. The doctor said my father was in a very serious situation, and, he might need an operation.
24 hours have passed. Nothing has changed. I have to stay at the hospital. I will let you know if there is any good news.
I am sorry again and look forward to seeing you soon.
Yours sincerely,
Tom Williams
