A Letter for a Friend

I am at my desk. I have paper and a pen in my hand. I want to write a letter for my friend. I write, "Hello. How are you? I am happy today. I have a snack to eat. Can you see me at three?" After I write, I go to the door. I see a tree and two women. They are happy. I go to the house of my friend. I put the letter in the door. Now my friend can see it.
