Inspired by 13 scary things that always happened at school I started thinking of the grown up, work, equivalent.
I thought of three before I started to get paranoid, a bit bored and realised I should actually be doing some work.
1. Turning up to work in your walking-to-work runners and realising you've forgotten your work shoes, and you've a meeting.
2. Calling your colleague, or worse still your manager, your boyfriend / girlfriend / husband / wife / child / dog's name.
3. Sleeping in and waking up with precisely enough time to get to work, if you don't have a shower, never mind get a coffee.
