You cannot comprehend
I would like to dash off a quick email to thank you all for participating in the OPERATION WRITE HOME project. You cannot comprehend how great it is to have this resource available when the PX no longer sells greeting cards or post cards. Your contribution has made the spartan existence here in Afghanistan much more tolerable. I write my wife a letter every day, and the cards you provide make it easy to send her a card when I don’t have time to write out a regular letter. Again, thank you for your contribution, and keep up the good work!
