People who don't use their indicators when driving - it's literally the flick of a switch you idle b*stards, and keeps traffic flowing. Use them!!!
Cold baths/showers - genuinely puts me in a foul mood if I have to wash in cold water
Luke warm 'hot' drinks - have to nuke them in the microwave 2 or 3 times before I finish one as I just cannot stand a hot drink that is no longer volcanic hot. Get genuinely annoyed when my preferred temperature has started to drop
Same as above but with cold drinks - luke warm/tepid/room temperature?... nope, fuck off
Same as above with hot food. Piping hot or I'm annoyed
People who make baby voices or animal noises. I can't bear it, I really have to fight the urge to give em a pasting
Laziness - we all have our 'off days' I get that. I like the odd lazy day. But those that are habitually lazy, who make a career out of it and put more effort into avoiding what they need to do, rather than just doing it, piss me off
Corrugated plastic. The type of stuff you find on '3D' images. I cannot stand it. Hate hate hate it, can't touch it. And if anyone rubs it and makes that fucking awful squeaky scratchy sound they're seriously at risk of dying.
People who spit or litter - filthy bastards. Recently saw a couple in a McD's car park eating their meal in their car. When finished both just lobbed the empty packaging out of the car windows. Then smoked a fag each and flicked the butts out of the window. Then the man cleared his throat and gobbed out of the window before driving off and leaving it all for the poor staff to have to clean up. PIGS DH had to hold me back.
Bad manners - cannot bear people who will not exercise good manners and common decency. Refusing to move one-behind-the-other on a narrow pathway and shoulder-barging oncoming pedestrians is a frequent one that makes me angry. Or when you're in say, a clothes shop, and you're browsing the rails flicking through the garments, but El Bitchio has eyed you and starts wondering if you've found something she might like. She won't wait til you've finished in case you get that mysterious item she thinks she's entitled to and will just start leaning into you and pushing you aside to get at it first. Fuck off love and wait your turn!
People who brag about how much money they have, and insist on telling you how much they've spent on every little materialistic item they own, as they cannot let you go on living unless you know how they spent hundreds on this-that-&-the-other. Distasteful and annoyance inducing.
People who hint instead of just saying what the fuck they want/need, then get upset when you don't pick up on their stupid cryptic clues. I've become familiar with those that do this now, and I have started to spot the 'hint's' but I deliberately ignore them. If you can't be a grown up and just be direct I'm not acknowledging it.
....You know what, I could go on all night. I have a lot of issues, and I'm quite obviously not a 'people person'. This was cathartic though OP, so thanks!
