You aren't an ass hole for saying no you're an ass hole for slamming the door on his face. You can say no with out being a bitch (and probably waking other neighbors up with their tantrum. As much as they love whinging about neighbors making noise).
I'm not saying this to be rude in any way, but I am guessing you have been fortunate enough to have never actually lived or worked anywhere that regular interactions with aggressive, entitled, mentally ill and/or heavily drug addicted bums are impossible to avoid. I can't speak for everyone, but holy shit can it wear down any sympathy
fast.
If some neighbor she's always been friendly with knocked on her door early one evening to borrow, idk, a cup of sugar or something, and Staph just randomly slammed the door in their face out of nowhere, then I'd agree it's a dick move. This isn't that. Some crackhead has been repeatedly bumming money off her and never paying her back, and even after Staph's mom explicitly told him his behavior was unwelcome, he wasn't getting any more, and it's time to knock it off, not one day later he decided it'd be appropriate to bang on her door at 2:30 am to hit her up
again. If there is ever a circumstance where a person is perfectly entitled to slam a door in someone's face, this is it.
Seeing her constantly blunder into absolutely retarded pajeet scams one after another is fucking hilarious, and Staph is enough of an entitled fraudster leech herself that I don't feel bad for laughing. The basehead fuckups taking her money are useless, exploitative, degenerate social parasites on the exact same level Staph is, but also with the audacity to actually get up in people's faces at whatever ungodly hour to subject them to aggressive begging. That earns a higher rank on my shit list. Staph isn't pounding on my door at 3 am until I literally cannot ignore it so she can demand I buy a patch, know what I mean?
That cat's way too fucking fat. How can Staph be so neglectful of the cat's every other need and yet feed her to the point of morbid obesity in less than a year?
My guess is Staph is always super absorbed in scrolling social media/reading fapfic, eating, and farting into the couch, and probably just finds it an annoyance when Siggy is playing, trying to get some attention from the only other living being in her world, or generally behaving like a cat. So rather than interact with the poor kitty, Staph just shovels treats into her face to shut her up because it's easier. I understand that there are times you're in the middle of something and if your cat wants undivided attention at that moment, they may have to wait... but this bitch has absolutely no life and supposedly wanted a cat more desperately than she has ever wanted anything, so there's really no excuse for this.
Tattoo-getters: how rude is it to bring this level of tattoo art in from Etsy instead of asking your prospective tattoo artist?
I mean, depends on the artist? The good artists I know are totally cool with people bringing their own drawings or designs they've found online for inspiration, so they can design you a piece that works with their style and is at least somewhat original. Most artists, though, realize that most tattoos people want are retarded. For every expensive, multi-session custom artwork that they're excited to put in their portfolio, you get fifty people in for small, quick bullshit like barcodes, barbed wire, dolphin tramp stamp, their girlfriend's name, or simple lineart ripped directly from the first page of Google Images. As completely uninspired as that shit is, it pays the bills, so they generally just do it. Really good artists might have an apprentice to whip off the basic shit for $150 a pop so they're free to concentrate on the ones they find more creatively interesting. However, it should be noted that if you rip some basic bitch clipart off Pinterest, flip it horizontally, and try to claim it's an original drawing you did, you're not fooling anyone. It's immediately obvious and you are being mocked behind your back.
