Gentlemen:

Our two firms have been doing business together for a long
time.  Perhaps that is why we cannot understand why you
haven't responded to any of our reminders advising you that
your account has fallen seriously behind.

We are here to listen if you are experiencing a problem and
we are most anxious to maintain the goodwill that we have
shared for so many years.

We will not even request your payment in this letter, but
merely urge you to contact our credit manager.

Let us hear from you soon.
