These past few days, I have:

- accidentally told a phone company I was married when trying to set up an account with them
- had my mind go blank at the bank when asked what I was there for
- been told something was only £1 when I thought it was £2 and still handing over £2 anyway
- gone to the wrong reception in the health centre and then missed out part of the form I had to fill in to register with them, meaning I got called back by the receptionist

all because having even a slight case of nerves when doing something seems to turn me into a complete idiot.
