How it works

Every one of these friendly letter writing prompts has a reader: a pen pal, a grandparent, a friend who moved away, someone to thank, or you a year from now. Each says three things to put in the letter.

Read the full guide

Pen pal writing prompts

Fifteen letters are to a pen pal, and each keeps to what someone far away could not guess: three words people say where you live, the game you play against a wall, what four days of rain did to the week. One asks three questions and answers them first.

Where a prompt goes in the letter

A prompt here fills the body, the main part of a letter, and the line under it is a sentence to put straight after Dear and the name. The three things to tell can take a paragraph each.

  • Write the date at the top. A letter to your future self needs it most.
  • End on a question. It gives the reader a reason to write back.

Questions and answers

What do you write in a friendly letter?

News the reader does not have yet. These prompts pick three things each time: for a grandparent, one thing you made this week, one thing you learned and one thing that made you laugh.

What are the five parts of a friendly letter?

Heading, greeting, body, closing and signature. The heading holds your address and the date, the greeting is Dear and a name, the closing ends the letter, and you sign your name under it. A postscript, P.S., can follow.

What is a good letter to future self writing prompt?

One that writes down small things before they change. Write to yourself a year from now about today: what you ate, what you are wearing and what you are looking forward to. Fifteen prompts here are to a future you.

How do you start a thank-you letter?

With the thing itself. The fifteen thank-you prompts open on what was given or done: It is on my shelf where I can see it from bed. You let go of the seat and did not tell me.
