So I visited my aunt's house a few days back.
They heard I write code (read: Google and copy-paste from Stack Overflow), and wanted me to help repair their computers.
Saw my cousin playing Battlefield 4 at sub-20 fps with a GTX 750 Ti on the lowest settings. His fucking CPU fan was bust, and judging by the amount of dust in his system, I literally thought he was cramming dust in there on purpose.

After a heavy dusting, another stick of RAM (4GB -> 12GB), a new heatsink (CoolerMaster T400i), and a fresh copy of Windows 10 (along with Office, etc.), he could play games at 60+ fps again.

What do I get? Not even a fucking thank you. Just a "you done yet? I want to play video games."
I mean... Gee. Your cousin flew all the way to a new continent, spent his precious vacation time helping you out, and all he gets is a cold-ass shoulder.
Even my fucking ex gave me more than that.

Don't you just hate it when someone borrows things from you and they don't even have the common decency to give it back the way it was borrowed.

Like come on! You borrowed my charger and gave it back to me without its head. Then when I asked you to find it you got mad. Is your fucking head straight? You even had the guts to shout at me. Stop playing like you're the victim and get real.

Spends 9 months on the side developing a library for analysis of a specific programming language. No help, entirely my own work. There's various tools built upon this library. Incorporates project management, an effective build system capable of parallel and distributed builds, a packaging system...

Beta release the library. Wait four months. Ask the community for who's been using it so I can get feedback and other comments. Majority of the comments follow a specific pattern.

"You don't support X, how dare you!?"

One, this is free software, pay me if you want specific things.
Two, I'm the only developer of a project usually undertaken by a small team.
Three, yes it does you fucking invalid... Every fucking time someone claims it doesn't support some feature, it's something I've already written and validated. I swear to fucking God users can't find something themselves and instead of checking the Wiki or asking for help, they blindly assume they can't make mistakes and it must be my defect.
