Unreliable Narrator

I’m not easily annoyed. I deal with people for a living and I’m use to working with the obnoxious. Of course, everyone has their exceptions, and he is mine. I told Davidson that I was iffy about working with him, but no, he assigns him to me anyway. I don’t understand how he even got this job to begin with. I know it appears to be pretty simple and that anyone could do it, but that’ isn’t true. It does have it’s qualifications, and this guy meets none of them. I’m convinced he cheated his way through school.
On top of being under qualified, he’s also a jerk. That’s putting it simply. And kindly. If you are going to work with people all day you have to be open minded, non judgmental, kind and courteous. He is not. No surprise. Just look at him! Always with the jeans with holes in the knees and polo shirts that are never ironed. The guy doesn’t own anything that could be considered “dress clothes.”
Alright, so we work behind a counter most of the day, scanning books and filling out forms and typing away at ancient computers, but we are still expected too dress nicely, thank you very much. And even if you don’t worry about his clothes, just his name gives you a sense of what this guy is like. His real name is some old Hebrew name or something. ‘Micajah’ I think is how it’s spelled. He could have chosen a normal nickname, like ‘Mica’. Of course didn‘t, though, because that would be too simple and too normal for him. Instead he has to go with ‘Cage’, “Just call me ‘Cage’.” Give me a break.
And he’s far to curious. I have no problem with the inquisitive but this is just too much. Every day it’s new questions about me. Where I went to school, if that’s my natural hair color, if I always wanted to be a librarian, what’s my favorite type of sandwich, have I ever been married, yada, yada, yada. While it would still drive me crazy I probably wouldn’t care so much if he was doing this simply out of the desire to get to know his colleague and supervisor better, but that isn’t why he does it. Oh no. He does it to annoy me - on purpose! He’s constantly grinning at me like he knows something and if I slip up and reveal an even slightly embarrassing fact about myself or let him know that a certain topic is touchy to me, he’ll exploit it.
I’ve talked to Davidson about him numerous times since he came here two weeks ago, but my boss seems to be oblivious to this guy’s undesirable traits. I’m not going to worry too much, though. I’m sure he’ll slip up in the next week or two and then it’ll be adios! Maybe then things around here will get back to normal.
