The tenth message
Dear Dr. M. Susan Stiner,
I'm very pleased with the mail you gave me the other day.
You wrote me a lot of message that are really useful and interesting.
Thank you so much again.
I'm afraid I couldn't send you many message as my preparation
wasn't good enough. Let me forgive my impoliteness. One thing I want
to tell you is that I really appreciated for your kindness.
Sincerely,
Fumi
