Hey, Halloween's coming up soon. I was just wondering what you and Mabel were gonna be and don't try to hide the fact that you and Mabel still go Trick-or-Treating. I know you guys still do. Don't worry; I think it's really cool. Actually, Tambry convinced me to go Trick-or-Treating with her as Marceline (me) and the Fire Princess (her) off of Adventure Time. So I'm excited for that. I just wanted to say I love you and make sure you were doing ok.
Love,
Wendy

Hey, yeah me and Mabel are going trick or treating this year. I'm going as Superman and Mabel's going as Wonder Woman. I'm glad you're going trick or treating too. By the way I watch Adventure Time once in a while and it's a pretty good show. I love you too, I really miss you.
Love,
Dipper.

Happy early Halloween! I'm so excited! Halloween is by far my favorite day of the whole year. Sorry, I know that's childish, but I really do like it. Anyways, how did you guys do at the talent show? What did you sing? Did you have fun? Are you getting tired of all these questions? I love you. Hope school gets better for you and don't worry I will take advantage of Middle School while I still can. I love you.
Love,
Mabel

Hey, Happy early Halloween to you, too. It's okay, Halloween is a pretty cool holiday. I'm planning on going to a Halloween party with Thompson, Lee, and Nate, so that should be fun. My band did great; we sang a song we wrote. No I don't mind all the questions. I'll try not to let my last year of school suck and I'm glad you're going to enjoy middle school. I love you too.
Love,
Robbie.
