Writing is reborn! to my dismay

I am really beginning to realize how very blessed I am to be Homeschooled. i have also realized that unfortunately I have been abusing my power. like in the writing department. I utterly despise writing. But unfortunately I am quite good at it. It seems I just need to be motivated. So i have a short story to write as one of my projects. So here is a little of the first part of my story, One Warm Spring. comments and ideas are appreciated.
Well here it is.

“Bob! Stop yer dawdlin’ an get down here!”
Suddenly remembering what he was up there for, Bob resumed his duties and went on to brush down the horse’s mane. “You must have quite the life, huh Shadow? You just do your job and everybody loves you, feeds you, and takes care of you.” “Are you talkin’ to that horse again?” It was Tom. His real name was Morgan, but he punched out the last man who called him that. Not that the man goes lookin for fights. That’s just not Tom’s way of life. He’s a real peaceful guy, but with the heat of the Texan sun, the with the Mexican Army breathing down your neck, people get a little antsy. And though its spring time, it feels like summer all year long.
“Bob if you spent more time concentrating on your work you would be able to get done a lot faster,” said Tom. Bob looked over to see Tom leaning on the frame of the stable with one of the widest smiles he ever knew. He was standing with his unsheathed buck knife, running over the edge with his thumb.
“And I suppose you’re workin hard? Or are you hardly workin?” said Bob. ‘Cause if you’re neither, you’re in more trouble than I am Mr. Travels.” Tom let out a chuckle, ‘You’re something else kid. But we have a reason to be easy. Word is that reinforcements are a comin’.”
So this was this look that Bob had been noticing. He may be just a lonely stable boy, but he wasn’t dumb. Being around animals so much, one gets to understand them just by the way they act. And Bob had noticed something that had been stirring in the attitudes of the defenders of this mission. Something more than hope, it was relief. Even the idea of fresh fighters instilled courage in the very heart of the Alamo.
“Don’t listen to this here fool Bob!” Then coming from behind Tom came Andrew Harvestings. “Are you givin this little boy false ideas here?” asked Andrew.
