It’s bad when:

• You run your finger over a mark on your new LCD monitor, and think it’s actually a gash. It’s better when you realise it’s just a stray gob (I wonder where from.)
• You’re reading a Pootergeek post and you realise you have no idea what the hell is going on, but you continue because you’re sure it’s very clever and maybe one day you’ll understand.
• You’re sitting on the toilet and a wasp flies in
• You realise you know more about US politics than UK
• You try to rescue a daddy longlegs (crane fly, for non-UK readers) and it lands on your face.
• You find yourself talking back to (stupid) newspaper articles. On every page.
• You discover that everybody in the country has memorised their national insurance number…except you.
• You remember to take your cheque book somewhere, fill it in, realise you’ve endorsed it to Mr Fifty-Two Pounds by mistake so rip it out only to discover it’s the last one.
