Today， when I went home after school， I saw the delicious snack， so I wanted to buy one of the snacks， then I could not find my wallet， I searched it many times， at last， I had to admit that my wallet was lost. I felt so worried， so I turned back to find my wallet， I watched the road carefully， suddenly， a black dog was in front of me， I felt so scared. The hog yelled at me， so I ran， the dog run after me， I run into the shop and got rid of the dog. I have to went home because of it was dark， my mother came out and told me I forget to bring my wallet， how stupid I am.
