Dear Jane,
I felt so excited after receiving your letter, thank you! Well we don't exactly celebrate Halloween but some does. Its also fun and horrifying. I think I should try celebrating it with my friends too! I will wear a vampire costume and visit some places at midnight with my friends. It will be cold outside though, but still we can't miss this amazing, scary day! After visiting, we will watch some horror movies and play some games. It will be also great to watch horror 5D and take pictures of horror scenes. Oh! That's nice of you that you want to learn Japanese. I would like to learn Korean, because I'm a big fan of korean dramas.
Your friend,
