Think about what you're going to write first. This can be tough.
Then write your idea on "paper" with a "pen" or "pencil". You know. Those things they had before computers
Now put the paper with writing on it into an "envelope" and write the name and address of your friend on the back. The post code is important
Now put the letter in the envelope, and put it in a post box. The post man or woman will do the rest.
Your friend will get the letter unless you forget to seal the envelope. I forgot to mention that. They will read it and hopefully write back!
- Pencil sharpener (optional)
- A friend
