Hmmm…what could this proposition be? You’ve got some great imagery in here so far. The line about the staring contest with the grass was a good visual, and it really, uh, “tickled my fancy” (another fun line).
I would watch out for run on lines, cuz they’ll make your writing seem muddled. I would change the second sentence so that “…he thought to himself.” and the dialogue before it would be its own sentence. So, the part about the horse nudging the guy would start a new one.
Ehh thats kinda jumbl-y. Note me if you need clarification. Anyway, good piece. :)
