Dear Prof. Lauer,
I hope you are doing fine. I am now in Saitama, but will go back to
Hiroshima to attend the conference. We would like to visit you to say
thank you for your cooperation. During this week, WED, THU, and FRI,
please let me know when you will be in your office. We would like to visit
you shortly.
Sincerely,
Toshiko
