Would you please mail these letters, Lucy?
Yes, Sir.
These two are urgent letters and should be sent by registered express airmail. Others are ordinary letters.
All right, who should I send them to?
It ' s sent to Mr. Charles. I believe he is in London.
Ok, home or office address?
Office address, please. He might be at work when they arrive.
Should I enclose this commercial paper with these two letters?
