Dear Mr.David,
Hello! You might not know me, but I sure know YOU! I am one of your biggest fans- no, fan GIRLS! Well, when I meet you this summer, I'm gonna give you the BIGGEST hug EVER! So if you see me(which you will), come say hi! I mean, videos on YouTube show me that you're a pretty nice guy-and I really hope that's true...
So...good luck with your career and stuff...yah.

Sincerely,
Julia, your biggest fan ever.
(P.S. My sign on tour has Earth and a cookie behind it.)
(P.S.S. You look really cute when you cry.)
