Hard to choose. I am fairly quick to get annoyances, but I also loose them really fast. So most of those things aren’t really worth my effort and attention.
Some bigger annoyances for me are…
…improper use of language, grammatically speaking, both in writing as well as spoken. In English these are more often than not written things like typing there when you mean their or they’re and your when it should be you’re. And! Of when it should be have or ‘ve (should of, would of and so on). Obviously in this case, dyslexics are forgiven, but the general population that has had at least some schooling should just know this.
In Dutch these are generally spoken things. Something I hear a lot lately is the mangling of irriteren en ergeren. Many people say irriteren aan. It’s not possible to irriteer aan. Ik erger mij aan dergelijke mensen. Deze wijze van taalverprutsing irriteert mij. Ik irriteer mij daar niet aan, want dat kan niet.
…people talking “small talk” to kids. Turning every other word into a diminutive as if they otherwise can’t understand you. Kids understand way more than they’re given credit for and deserve to have their voices be heard.
…people that take their first impression of something and use that to form an opinion and a judgement. Without looking beyond the initial image, without doing some research, without thinking things through. Everything has multiple sides to the story, and nothing is ever as black and white as it seems. So do your research before you spout opinions and don’t be afraid to admit it if you haven’t. There are many things I don’t have a real opinion about (beyond first impressions) because I haven’t looked into it.
