Appreciation letter

　　I

　　Dear Sharon,

　　I am writing to tell you how very much I enjoyed the days at Chicago.

　　Everything was just about perfect. You certainly know how to make a guest feel at home. Your delicious meals were a treat, and your flexibility in adapting to my irregular schedules made many things possible.

　　I hope you and Peter know how I appreciate your hospitality, and your many kindnesses to me. I count myself fortunate indeed to have two such generous charming friends!

　　With thanks again and best wishes to you.

　　Yours

　　Alice

　　Dear David,

　　I would like to take this opportunity to express my heartfelt gratitude to you for your very active participation in our recent conference in Montreal on the future of aviation. The chairman and board members have also asked me to pass on their sincere appreciation for your efforts in supporting the institute in this important undertaking.
