Dear Matt & Amy,
I would first like to tell you that I met your children at the Del Mar fair this past weekend. They were sweet and even let me take a picture with them. I would of loved to meet you too. I just want you both to know that I watch your show a lot and I would like you to know that you guys are amazing people and very great parents! Thank you for sharing your life with viwers/fans like me.

Sincerely,
Alex

P.S Your kids might remember me as the girl who took a picture with them by the Ferris wheel.
