"Dear Paul:
Today I am leaving the US. Looking back on four exciting weeks. A large part of
the excitement results from the incredible welcome I received from you and from
all the other staff in your dental office. I feel privileged that you openly shared
your knowledge and experience with me and so gave me the chance to excel in our
profession.
It has been a great time and I am very much looking forward to keeping in contact
even beyond these few weeks.
Thank you that you extended your friendship to me.
Your friend..."
