Dear Austin Parker ,
We are so pleased and touched by your efforts in making the tree planting project a great success. It was really more than what we expected! Both the non-government organizations and our city officials were greatly impressed. It was amazing how you convinced and influence so many people to join. Indeed, we are lucky to have you on board. As our way of saying thank you, we have included herein a gift certificate just for you.
