Dear My Boss：
I am very sorry for missing the presentation which was scheduled on May 4 20xx, regarding the environment change review in our company. My friend was very ill and he was hospitalized since last 3 weeks. I had to take care of him and that's why I was not able to make it for the scheduled appointment.
He came to Shenyang for a trip and I was his only former classmate here and no one else could help him and take him to the hospital. Now He is fine and I think he is able to find his way home by himself.
I am requesting you to arrange my presentation as soon as possible. I want to thank you for your understanding and patience. I am looking forward to the next presentation when I won’t miss that no matter what.
Best regards!
WangWeijia
