I do not like people who stereotype others. It winds me up that people can't see past a generalised view which is usually false and sometimes offensive. I also small things like people who will cross the road where they are, causing a disturbance, when there is a specific crossing down the path.
On Toluna, I really don't like it that people do not rate the opinion. We are all happy to say what we think and like to say whether other peoples opinions are useful or not but we won't rate the opinion in general. It is simple to just click the stars, please do it.
People that cut you off mid sentence who think their point is more important/ just feel the need to waffle on! So you could sum acts like that up as rudeness. If you've been watching the Apprentice on Tv, the characters of most of the people in the competition annoy me, and I feel all of them think too highly of themselves with a 'heave up the ladder, i'm on board' sort of attitude. Although I live in London, it annoys me how people seem so rushed, all the way through to old age, which is a major stress factor.
spitting in the street, hawking and sniffing on the bus, people coughing and not putting their hand in front of their mouth. generally poor hygiene related activities/actions.
When I'm trying to go shopping and people with push chairs take up the entire aisle, like they are entitled to all the space they want. Especially if the shop is little, just leaving the push chairs all over in everyone's way. Or people who just stand in the middle of the aisle, who refuse to move even though you have to shove them out of the way.
I cant stand the "know-it-alls" who have a loud and rather bombastic (bludgeon you over the head verbally) type of response to anything and everything. They usually put down anyone who is a bit hesitant about an opinion, subject matter or current event so that the person meekly backs down when in fact, they could actually be right and not the know-it-all. My favourite phase to people liker these is "W..h..a..t..e..v..e..r!" That really winds them up.
people who chew gum, people who throw litter, people who are too lazy to work, people who have kids just to be in fashion and to get a bigger house - I could go on all day!
