Dear Li Hua,
How excited I am when I’m accepted as a volunteer of WCS! You know I have been saving the abandoned animals. So in this upcoming summer. I can do more to help the lovely animals and even the endangered ones. And I really expect you to join us! I am sure we will make a difference to nature and people!
Yours,
Jim
