Once upon a time, in a small town, there was a helpful girl named Mia. Mia loved to help people. One day, Mia found a letter on the ground. It was a very important letter for Mr. Brown.
Mia said, "I will take this letter to Mr. Brown." So, she went to Mr. Brown's house. When she got there, she saw a big dog. The dog was very loud and scary. Mia was scared and did not want to go near the dog.
Mia called out, "Mr. Brown, I have a letter for you!" But Mr. Brown did not hear her. The dog was too loud. Mia felt sad because she could not help Mr. Brown. She tried to get closer, but the dog scared her away. 
Mia lost the letter when she ran away from the dog. She felt bad because she could not be helpful. The letter was gone, and Mr. Brown never got it. This made Mia and Mr. Brown very sad.
