Blue - a short story

She was exhausted and did not really know what to do. Katie was running over a bridge. It was a very long bridge and it was big. Really big. Katie did not know its name, but this was not important to for her at the time. The sun was shining brightly, there was a blue sky and some cute clouds like small fluffy sheep - a crystal clear view. It was a nice day, maybe a bit too hopt, but that was okay.
The sun was shining down on her, but Katie was not sweating. She was running like crazy. Her legs moved quickly. A few cars drove by and Katie's blonde hair was going up and down, up and down. Up and down to the rhythm of her feet. Running, running, running. Katie was still not sweating. The sun was still shining down on her. Her legs moved step by step. A few cars drove by. Step after step.
She still couldn't see the end of the bridge. "Maybe the bridge does not have an end? How should I know?", Katie thought. The sun was shining. Running. "Just run!", she said to herself.

Suddenly she stopped. She looked down at the river under the endless bridge.
She stepped on the railing. She didn't wait. She jumped. Katie was not sweating. The water was coming closer. Blue water. Blue like the sky above her.
Katie liked this colour.
Blue.

Notes: bridge is spelled with a "dg", not "gd".

The red marks are grammatical/spelling errors, the green marks are words that are needed to complete the sentiment. The sentences without the green words just don't sound right.
