Dear Jenny's Momma,

I'm writing this note because last Sunday I forgot to thank you for the delicious birthday cookies you made for me.  Because I don't know when I'll see you next, I wanted to show my gratitude before the remarks were too dated.

It was very thoughtful of you to go out of your way to bake for someone you had only met twice, and I was very touched by the gesture.  Let me say, flattery aside, that these were wonderful cookies.  Everyone at work enjoyed them as well.  You were a hero in the office that day.  "Jenny's mom sure makes good cookies," was a common phrase around the water cooler. 

I have enjoyed oatmeal cookies many times in my life, and I love chocolate chip cookies as well.  But last Friday was the first day that I ever eaten an oatmeal chocolate chip cookie.  It was an enlightening experience; my eyes were opened up to a new array of dessert possibilities.  Never, in all of cookiedom, had I dreamed of such a marvelous pairing of oatmeal and chocolate.  

You took the best attributes of my two favorite cookies and combined them.  Sort of like how geneticists dream of creating a hybrid animal with the speed of a cheetah and the strength of a gorilla.  You're the Doctor Moreau of Toll House. 

Please do not take any of these remarks for sarcasm, or mere flattery.  I might have simply said that I liked the cookies, but I was afraid you wouldn't take me at my word. 

Sincerely,
