V. Gratitude, thanks.

Gratitude, thanks or appreciation should always be expressed to the person that was so kind as to help, serve to the person asking for it. For example:

Thank you very much for sending me a reprint of your article …

- I want to thank you dearly for all that you have done for me ….

- Please, accept my sincere appreciation for all your efforts.

Dear Francis

Thank you very much for the book which arrived yesterday. You have no idea how grateful I am for all the troubles you have taken. My work will be much easier now. Please, let me know what I can do for you. Thank you again,

Your grateful friend.
