Hello, Dr. ...

This is the mother of C. I haven't got any news about C for couples of days, which makes me a little bit worried. I don't know what is going on. Could you please help to contact him, and ask him to make a call home?

Thanks in advance for your help.

Best Regards,

...

Hello, Dr. xx,

I am C's mother, and haven't heard anything from him for several days. I am very anxious and wonder what happens to him. If possible, could you ask him to give a call home. Thanks a lot.

Dear Dr. X
