If you would like to thank someone for their support and cooperation, here is a simple template you can use to write a thank you letter of support and cooperation.
I can’t thank you enough for being there during the times when we needed you the most. We recently experienced grief and sorrow since one of our most beloved recently left us. Good thing, we have great friend such as yourself to console us during these difficult times. I don’t know how I can get over this feeling but your presence will certainly help.
We all know life goes on after major tragedies. It is only right that we only comfort each other during these times. You can bet your bottom dollar that I will also be there during your tough times.
