People who park badly, people who don't use their indicators, drive too slowly or are just crap when ambulances are trying to get past, stopping in the middle of the road in a flat panic DOES NOT HELP!! OK thats most the road rage ones...
Boy racers on my street who accelerate to about 50 then have to squeal to a halt as the road is only about 200 metres long! And beside a school. Dog crap, on my doorstep. One day when I can be arsed to get up early I am going to shout very very loud abuse throught the letterbox! Drunk people coming out the pub down the pavement to about where my front door is and having a screaming match which sounds like its in my hall.
People who shout sarcastically 'DON'T MENTION IT' when they stop at a zebra crossing for you, OK I do usually say thanks, but it is a requirement in the highway code to stop and not expect gracious praise and adulation for their kind deed.
People who don't wash before they get in the swimming pool.
My DH saying either, ither, or, instead of just one of them.
People who work in bars who say do the international hand symbols for small, large, ice, lemon. We don't need visual clues as to how big large is, we can understand the word alone ta.
I am quite a narky person ;) Theres hundreds more...!
