As far as the quality of the writing, technically, it is difficult to judge. Most of it is dialogue, so liberties with the language may be attempts at character. The attempt to portray character through angry words is an immature writer at work. Character comes out through action, and there is very little action in either piece. It's a common mistake.
A friend of mine teaches business at a university in New Jersey. On occasion, we'd have a couple of beers and he'd read some examples of what his students submitted for grades. I think he was trying to get me to come up with a creative way to say 'F.' Some of it is uproariously funny; I would have repeated at least a year of high school if I wrote papers like that. Grammar, spelling, and syntax are alien concepts to many students who were raised in English speaking households. But none of it rises to the level of anger in these two examples. I wonder what his other writings are like.
Well said friend.
