Show not Tell

1. Felila was exhausted.
Felila flopped onto the grass after completing the run. She huffed and puffed. She lay there until the last people came back. She picked herself up and trudged back to class.

2. Russell was hungry.
Russell walked around, staring enviously at other peoples lunch.

3.  Troy was lying.
Troy knew that he could not tell them. He was called into the office. He told what happened. His eyes darted to the left. His hands were sweaty. 
They brought in a witness, who saw everything unfold.  His hopes fell.
