I can't believe I actually this this whole thing.
What the fuck are you even doing, this is some incredibly amateurish shit. If you ARE an incredible armature, then ignore these scathing remarks and just take the criticisms. If you've been trying to write for more than two months, then I'm afraid you have no discernible talent.
What tense is this thing even trying to be in? Obviously it's first person, but you can't seem to decide if it's the man dictating his actions as they're happening, or dictating it as if it already happened. All these things like "Were moving" instead of "moved" really add up when it's hard to tell what the fuck is going on and makes it read like ass because you're missing out on how the character might react to these situations as they're happening, instead of making it sound like he's DESCRIBING how they happened, even as he's RIGHT THERE.
I'm not sure if you're a sociopath or just haven't read enough books or talked with enough human beings to be able to write what humans sound like, but the main character is not a human. He is a robot. He is a cold, calculating robot that pretends to be human, but is dictating everything so matter-of-factly and with janky sentences with no resemblance to the thought patterns a normal human may have. You didn't write the character "Mr. A" like a human being, you wrote him like the CONCEPT of an asshole boss. You're detaching the actions and decisions so much from the main character it's disorienting.
This time, I walked nonchalantly, thinking of an excuse that would lighten the reproach I would receive from Mr. A when I got to work.
Sounds like fucking shit. Make it instead something like,
This time, walking nonchalantly, I thought of an excuse that could lighten the reproach Mr. A would give me when I got to work.
And honestly that still sounds like ass, but I can't get any better without completely rewriting it.
You're separating subject and verb too much, and making sentences where the whole purpose of them isn't established until the very end. What's worse is you're making entire pointless clauses separated in parenthesis so long that anyone reading it would need to reread the subject to remind themselves what the fuck the sentence was even about by the time they reached the end. Get the point across, THEN, deal with idle bullshit. If you're dealing with action, make the sentences punchy and make sure the reader immediately knows the gist of the sentence, if you're describing things, feel free to get a little long winded, and please for the love of God read this shit out loud to yourself. You'll be able to intrinsically understand why the fuck your sentences sound like shit and are so obfuscated it takes anyone reading it out of the action (or lackthereof) because they need to waste extra brainpower trying to figure out what the fuck you were talking about.
Also, if you were trying to be "artsy" save it for when you actually have talent.
