Dear John, what is your fear? What are your secrets (can you tell just one)?

Dear Rebecca_Dolenz ,
Here is the airplane kit like you wanted. I was looking forward to giving it away. :)
This is kind of embarrassing, but one if my biggest fears is rejection. I know it may not seem that way, but that's one of my fears.
My secrets, huh? You're getting kind of personal, but I guess that's what I'm here for. You've probably already heard about the "big one" from Yoko. Another secret is that I wish I was a bird so I can fly and be free. Cue "Free As A Bird," please! I love birds. They don't have any worries and all that, so I wish I was one. That's one of my secrets.
Thanks for your letter!
