Creativity takes over

So this is a story which I wrote at about 5a.m. tonight for one of my courses.

Elijah, a five year-old, was sitting at the kitchen table, staring at the endless hills outside, which contained all possible shades of green, roughly interrupted by some red, white or pink bits of blossoming wild flowers. He was alone in the house. Alone, but not lonely. He was used to this feeling, waiting for his dad to come home from the corn fields. It’s been like this for a long while, that actually lasted more than he could remember. However, when he was way too little to be left alone, his aunt Cora would stay with him throughout the day, talking to him, sometimes calming him down so that he would stop crying. He was such a cry-child! He took her as a family member. But as he grew old enough to stay alone in the house for the whole day and do some cleaning, she became a guest, a visitor. She would come once a week, every Thursday. More and more often, talking to her felt completely different, strange, even awkward.

He saw Caleb walking across the tall grass towards the house, a chocolate-brown figure, surrounded by the greenness of the sun-lighted hills. He finished the day’s job and until the next day he was free. Elijah watched him, relaxed, getting closer and closer to the house, waving to him. The little boy waved back. He felt sympathetic to Celeb, although the old man did not seem to mind the obligatory work in the fields. Elijah might have to go and work there one day, too. Just like his grandfather did, just as his dad does. But he might as well not. Caleb told him that things were getting better, everything was changing. However, seeing his dad so lively and happy every time he was coming back from the fields, he felt like this kind of work was all he needed for a good life. It seemed to Elijah that it was enough to feel useful, enough to be treated fairly, to eventually gain respect from the whites, which, Caleb used to tell him, was an important goal to achieve. The door opened and he heard a cheerful and lively voice, calling his name. Impatient and excited, he waited for Caleb to take of his shoes, then jumped off the chair and ran to greet him.
