The little things (that annoy the bejesus out of you)
1. I work with this bloke in a small office, and at least three times (but generally more), he makes a sound like a boomerang is being thrown through the air. Why? He doesn't say. It was funny at first, but now it's become like a Japanese water torture method. Just shut up!
2. People who continue sniffing without blowing their nose. Sniffing is disgusting. It's also pointless: if your nose is running, then by sniffing you're just moving the mucus up ... in order to come down again.
3. My neighbours park outside my house. They have a perfectly good driveway, and a perfectly good bit of kerb outside their house for the purposes of street-parking. Well: I say they're perfectly good; but there must be something wrong with them, because they refuse to use either, preferring to park outside my house. Occasionally, they'll block my drive for good measure, and then look put-upon when I knock on their door to ask that they move their vehicle. Were it not for the fact that it'd mean they'd be there for longer (and the fact that I'm much too middle-class and mild-mannered), I'd slash their tyres.
