Dear Mrs. Abenathy:
Thank you for being willing to write me a letter of recommendation in support of my college application. This letter will give you a better idea of the classes and activities that I have been involved with throughout my high school years (also see my attached résumé).
The other people who I am asking to write me a letter of recommendation are Mrs. Hernandez (Spanish), Mr. Martin (English), and Mrs. Erickson (Principal).
I am asking each person to focus on different aspects of my background, character, academics, and activities so the college will get a broad sense of my life and skills.
