     When you are little, the whole word feels like a big playground. I was living in Conyers. Georgia the

summer is all happened. I was a second grader, but my best friend Stephanie was only in the first grade.

Both of our parents were at work and most of the time they let us go our own way.

     It was a hot afternoon and we decided to have an adventure in Stephanie's basement. As I opened

the basement door, before us lay the biggest room, full of amazing things like guns, dolls and old cloths.

I ran downstairs, and spotted a red steel can. It was paint. I looked beyond it and there lay even more

paint in bright colors like purple, orange, blue and green.

     "Stephanie, I just found us a project for the day. Get some paintbrushes. We are fixing to paint." She

screamed with excitement as I told her of my secret plans and immediately we go to work. We gathered

all the brushes we could find and moved all of our materials to my yard. There on the road in front of my

house. We painted big stripes(条纹) of colors across the pavement(人行道). Stripe by stripe, our colors

turned into a beautiful rainbow. It was fantastic!

     The sun was starting to sink. I saw a car in the distance and jumped up as I recognized the car. It was my mother. I couldn't wait to show her my masterpiece. The car pulled slowly into the driveway and from

the look on my mother's face. I could tell that I was in deep trouble.

      My mother shut the car door and walked towards me. Her eyes glaring, she shouted "What in the

world were you thinking? I understood when you made castles out of leaves, and climbed the neighbors'

trees, but this! Come inside right now! "I stood there glaring back at her for a minute, angry because she

had insulted(侮辱) my art.

     "Now go clean it up!" Mother and I began cleaning the road. Tears ran down my cheeks as I saw my

beautiful rainbow turn into black cement.

     Though years have now passed, I still wonder where my rainbow had gone. I wonder if, maybe when

I get older, I can find my rainbow and never have to brush it away. I guess we all need some sort of

rainbow to brighten our lives from time to time and to keep our hopes and dreams colorful.
