Three things that make me wince:
1. The idea of a vibrating razor.
2. The fear of forwarding the wrong thing to the wrong people, every time I press send on a sensitive email.
3. The memory of my first day in the coolest job I could ever imagine when I was 'cool' for all of about ten minutes - and then got the toggle from my anorak stuck in my chair wheel and I had to be rescued by a genuinely cool person.
*and of course, posting two days late - unlike the lovely Clare, whose idea this three things was and who always gets it right.
