“Hello Eugene,
Thank you for your great letter and many thanks for the time and effort and interesting information. I have already received enough mail that I know that such a higher degree of attention and care is not self-evident. Your card has given me great pleasure and the exact consideration great pleasure.
Best regards, Richard”
