You may have your own suggested reading. Finally, explain that you want them to tell you what they intend to do about the suffering of fish at their stores. Explain that you want a response to your letter. Thank Mr. Glass for his time, and end your letter. You may want to leave your letter to sit for one day, review it, and see if you want to make any changes.
Friends can offer good suggestions, too.
This will serve us in refining and forwarding our Walmart letter-writing campaign. We will also honor your efforts in our newsletter. Thank you one and all for your support. Let them know that you will not stand by as these fish suffer. Of course I was shocked.
