Dear Felix
It was certainly a pleasant surprise when your secretary called to arrange your visit to Springfield. When it began to snow, I feared we might have to postpone the meeting, but you were undaunted. Thank you so much for coming. It was good to meet a good friend after so many years.
Your visit was a compliment to everyone in our office. I wish we would have had more time to talk, but perhaps that will happen another day. Thanks for your kindness and generosity.
Regards
Lydia
