September 1981
Dear Mr. Pettigrew,
We would like to thank you for the useful information you have provided us with. We are very much honored by your continued trust, and have come to value you even more greatly as a friend and compatriot.
Always remember that when one does harm to one's friends, one tends to be brought down alongside them. Such are the ties that bind.
-Your friends
P.S. Please attend our meeting on the twelfth of the month, we are expecting a truly inspirational speech from the forefront of our organization. Shall we say that you know who it is?
