Go on, have a drink, take a seat, let it all spill out - what pisses you off ? It could be anything from society, people, internet, general life or Piers Morgan.
I'll start the proverbial ball rolling -
*Squeezing the last drags out of the toothpaste tube when there's next to nothing left.
*Someone entering your room and leaving again without closing the door.
*One word answers. *ESPECIALLY* to long and descriptive pieces of text which have clearly taken some considerable effort to write up. Really, there is just no excuse for it. Offenders need to take a good look at themselves in the mirror, then punch themselves in the jaw many times.
*People under the ages of 16 who cry about or take a relationship break-up really badly. Remove your head from your a*se and lighten up, no-one died and you're only young. It does not matter.
*The Daily Mail. Seriously, what ? Why ? What ?
*People who claim to have social anxiety but are very capable and confident in social situations that real sufferers could only dream about.
*Automatic doors that never work right.
*Noisy fellows on the bus. Point ?
*Hypocritical people as a whole, but ESPECIALLY those who always berate other people for judging others and being disrespctful to others and what have you... but they do it themselves. Go and play with matches.
*Celebrity Juice. I don't see the fuss ? Keith Lemon is just incredibly annoying.
*Jedward. Natch.
*Slow internet connectivity, even more so when you're watching something live.
Think that'll do for now.

Pleasantly surprised at how well this holds up for the most part, if viewing with a December 2012 lens. Only one I shudder at is the 4th point - cos believe me even if you're in your 40s and splitting from your wife, my advice is now the same. Enter the chaos mode and don't look back.
