How to write a letter to your best friend
Take notes.
It can be scary to sit down to a blank page and try to write a long, meaningful letter. Even though you know your best friend well, it can still be difficult to think of what to write.

Available options:
[I] As you go through your day, take notes of little things you think your best friend would like, events you want to tell your best friend about, or just things you find funny. Your friend will appreciate that you include these little details about your daily life in the letter.
[II] Take notes in the margins of your notes and keep them part of your writing schedule that can be viewed in the future. You can also give your best friend inspirational quotes or funny anecdotes about how important writing is.
