I used to work with a teacher in my last uni year.

The job consisted on doing a kinda-like management system for a business. It all began kinda "right", we agreed upon a price for 6 months of my work (a very lowball price, but it was just right because I was learning stuff that we were going to be using).

Fast-forward first six months, all I do is code frontend, mockup screens and whatsoever because this "business" hadn't give us proper requirements (Yeah, I told him to ask for them, but nothing came through).

So I was like well, I'll keep working in this project because I really want to finish it. Sidenote: I was doing all the "hard work", he didn't know how to code, and he calls himself a teacher... wtf).

Months go by, and a year goes round, in between these months, he spoke to me, that he wanted me that we kept working together, that we could renegotiate the payment (I asked him to give me my payment once the job was done). I agreed, but my uni residence period was coming along and I got an oportunity to go abroad to another country.

So there I was, in the need of money to buy my passport, plane tickets and other stuff, so I asked him for the payment.

Needs to be noted, that the last 6 months work was me doing tutorials on how to fucking use Linux, how to use PostgreSQL, how to fucking use CSS! He told me he would pay me extra for it.

The day came, and I received my payment... the exact amount we talked a year ago, I was like "Seriously dude?", but well, I needed the money and I didn't have time to argue, so we talked a little bit about me helping him and I told him "As long as I have time, I'll help, but remember that I'm going abroad to work for a small startup, so maybe I'll be up to my head with work" he agreed, we nod and then I left.

First week abroad came in and I was doing a shit-ton of stuff, then his first message comes around "Hey, I need more tutorials! ASAP! Before 6PM"

What.The.Fuck. I told you, son of a bitch, that I wouldn't be able to do them until weekend.. and it was monday!

So I ignored it, weeks went throught and my "angry mood" was fading away so I said to myself "Well, it's time to pick up that stuff again", I open Slack and I find a week old message with a document attached, it was a "letter", I just skimmed by it and read some keywords "deceptioned... failed me.."

Sure dude? Was I the failure? Becase, as far as I remember, you were the fucktard that didn't know how to fucking install a VM!

A week went by, and then randomly a friend of mine talks to me through Facebook:

E: Hey, how are you?
M: I'm fine, what's up?
E: What did you do to TEACHER?
M: Nothing, <explains all situation>
E: Well, It seems weird, that's why I wanted to talk with you, I believe in you, because I know you well, but TEACHER it's thrashing shit about you with all his students on all of his classes
M: Seriously?
E: Yeah, he's saying that you are a failure, irresponsible, that you scammed him

That moment, I for sure, lost all moral responsibility with him and thought to myself "He can go fuck himself with my master branch on his ass"

So when I got back to my country, I had to go around in school, avoiding him, not because I was ashamed nor anything by the way, just because I knew that If i ever had the disgrace to meet him face to face, my fists would be deep into his nose before he could say "Hey".

Moral of the story:
If you overheard that a teacher has a bad rep, not by one, nor two, but more than +100 people, maybe it's true.

Good thing my friends and others know me well and I didn't have repercutions on my social status, I'm just the guy that "fucked up TEACHER because I had the right and way to do it"
