Dear Felix
Thank you for extending such a compliment to me by inviting me to serve as an honorary member for your fund-raiser. I appreciate the confidence you have shown in me. Prior commitments make it impossible for me to attend personally, but rest assured that you have my full support in your objectives. As an avid supporter of your cause, I hope my modest contribution will help.
I sincerely hope your fund-raising attempts meet with great success. I believe that you will accomplish much good as you realize your goals.
Regards
Lydia
